What lives on a dock besides the door and the leveler

This page covers the gear around the opening: seals and shelters, bumpers, portable plates and boards, and dock lights and chocks.

Two things it does not cover, because they have their own pages:

And the door above the opening is either a sectional or a coiling door.

Seals and shelters

A compression dock seal uses fabric-covered foam pads that the trailer backs against. A dock shelter uses a frame and curtains that seal around the trailer; the curtains can contact its sides and top without compressing foam pads. The opening and trailer mix determine the right fit.

How they fail: tears at the top corner where trailers clip them, fabric pulled loose from the mounting, head pads collapsed and no longer touching, and the classic one — a torn flap that catches on the next trailer and can tear further.

In a Minnesota winter, a torn seal is not cosmetic. It is a hole in the building envelope at a bay that runs all day.

Bumpers

Bumpers are the rubber or laminated blocks bolted to the dock face. They take the hit when a trailer backs in.

Missing or flattened bumpers leave the dock face and nearby equipment more exposed to backing-trailer impact. The right replacement depends on the trailer approach, projection and mounting—not just the width of the old rubber block. If bumpers on two bays are crushed flat or missing, that is worth a call before further damage.

Worth reporting: which bays, whether the bumper is crushed, split or gone entirely, and any dock-face damage already noticed from a safe position.

Dock plates, dock boards and bridge plates: identify before you decide

This is the section most worth reading carefully.

A portable dock plate or dock board, sometimes called a bridge plate, is moved into position rather than permanently installed. Products differ in material, curbs, capacity and permitted traffic. The device’s identification and manufacturer rating—not its appearance or the presence of curbs—determine whether it can carry hand trucks, pallet jacks or powered equipment.

An installed edge-of-dock leveler looks a bit like a small board but is bolted to the dock face and stays there. That one belongs on the leveler page.

Now the boundary, stated plainly:

A damaged portable device is never assumed to be weldable, never assumed safe to put back into service, and never assumed rated for the truck that is about to drive on it.

Bent, cracked, curbs deformed, or a rating plate you cannot read — that call belongs to a qualified provider working from the device's own rating and the manufacturer's instructions. Not from how it looks. Not from a web page. And not from "it's been fine so far."

Dockboards in use sit under federal workplace requirements for dockboards and walking-working surfaces — 29 CFR 1910.26. Portable dock devices are also covered by the ANSI MH30.2 standard family; which provisions apply to yours is a question for the provider and the manufacturer.

Dock lights, chocks and the rest

Dock lights — the swing-arm lamps at the opening — and chock storage brackets are in scope. So are the small fittings around the bay. Powered communication lights and interlocks that talk to a restraint belong on the restraint page, because those are part of a signalling system rather than a standalone lamp.

Keep people and equipment clear of a damaged bay. Do not straighten, weld or "test" a portable device. Take the bay out of use through your facility's normal process.

Tell us which bay and what's damaged.

What to say when you call

Example wording for a first call. It is an example, not a script, and not a real job.

"The seal on bay 2 at our Shakopee building is hanging loose and catching on trailers."

Three steps after you call

  1. You describe it. Facility location, which bay, what is damaged.
  2. Your request may be shared. Calls may be shared with an independent commercial dock-and-door repair company.
  3. That company takes it from there. They confirm whether they can serve the address, what they can do, when, and what they charge — plus their own contract, work and warranty terms.

Useful, not required

How many bays are affected. Whether it was a single impact or gradual wear. For a portable device: what the rating plate says, only if you can read it from where you are standing. What kind of equipment normally crosses it.

You can call without any of that. The facility address, a bay number, and "the seal is torn" are enough.

If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.

Give us the bay and what you can see.

What we cover — and what we don't

In scope. Dock seals, shelters, bumpers, portable plates and boards, dock lights and chock storage at warehouses, distribution centers, manufacturing plants, cold storage, food and beverage facilities, fleet garages and other commercial buildings.

Not in scope — here is who to call instead.

  • The dock face, the pit and the slab → a concrete or general contractor. We can flag that it looks damaged; fixing it is a different trade.
  • Parts-only orders → a distributor.
  • Pallet racking, conveyors and shelving → a material-handling installer.
  • Dock lifts, scissor lifts and yard ramps → a material-handling equipment specialist.
  • Loose wheel chocks as a purchase → a supplier.

What affects the price

We can't quote your dock equipment repair from a web page. The price depends on the equipment, the damage, parts, and access. Here's what to ask before you authorize work.

Ask which kind of number you have: a call-out or diagnostic charge, a starting price, a scoped fixed price for named parts, an estimate, or a committed quote. Ask what happens if they pull the seal off and find the mounting or the wall behind it is damaged, because on dock equipment that is the common surprise.

What drives itWhy it moves the number
Opening sizeStandard and custom sizes must fit the opening and trailer mix
Seal versus shelter constructionDifferent products, different mounting, different price
Condition of the mounting behind the fabricThe surprise that turns one job into two
How many bays at onceDoing four bays in one visit is not four separate visits
Whether the dock face itself is damagedThat is concrete work, quoted separately by someone else
Non-stock sizes and lead timeCustom openings wait on fabrication
Portable device rating and conditionWhether the manufacturer supports repair at all

Ask what it will actually take.

Repair it, or replace it?

Seals and shelters can often be repaired, especially when one curtain or one pad has gone. What tips it toward replacement is fabric that has failed in several places at once, mounting that has pulled away, or an opening that has changed the trailers it sees.

Damaged bumper material may need replacement, with the mounting and dock face assessed separately. Ask whether the proposal covers the bumper assembly, fixings and any separately scoped structural repair.

Portable plates and boards are their own question, and the answer is not "weld it." Ask what the manufacturer supports for that model. If nobody can tell you the rating, that is an answer on its own.

The Minnesota rules that touch dock equipment work

A Minnesota residential contractor licence is not the commercial credential to look for. DLI says commercial construction contractors must register unless an applicable exemption applies, such as holding the relevant DLI licence. Registration is not permission to perform work that requires a trade licence. Check the company's legal name in DLI's licence and registration lookup and ask which registration, trade licence and local requirements apply to the actual scope (DLI construction contractor registration).

Adding or changing fixed dock-light wiring or a powered accessory can add electrical work to the job. Ask which licence and permit or inspection the specific scope requires; replacing a lamp is not automatically the same job as adding a circuit. Use the facility address to check state or municipal electrical inspection (DLI contractor guidance; minor repair and maintenance).

Portable dock devices in use are covered by 29 CFR 1910.26, a federal workplace rule addressing dockboards. That standard is background for why the rating question matters. It does not make a web page the right place to decide whether your plate is safe.

The provider and the issuing office confirm what applies. Full rulebook on the Minneapolis–St. Paul dock and door repair page.

For a facility in Wisconsin, use Wisconsin DSPS and the local building inspector, not the Minnesota permit route. Wisconsin adopted the 2023 NEC effective September 1, 2026 (DSPS notice); ask the electrical contractor which code and permit requirements apply to the work.

Dock equipment questions

Can a torn dock seal be patched?

Sometimes. The model, extent of damage, compatible repair material and mounting condition determine whether a pad or curtain can be repaired or needs replacing. Ask the provider to check the attachment and the rest of the assembly, not just the visible tear.

Our bumpers are gone. Is that urgent?

Treat missing or flattened bumpers as a problem to report before the affected bay is used again. They absorb backing-trailer impact and help protect the dock face and equipment; the provider needs to assess the mounts and the right replacement as well as the rubber. Do not approach the drive area to inspect them.

Our loose plate is bent. Can it be straightened?

Do not assume so, and do not try. A portable dock plate or board carries a load rating tied to a specific kind of traffic, and bending changes the metal. Whether it can be repaired at all is a question for the device's rating plate and the manufacturer's instructions, answered by someone qualified. An unreadable rating means capacity and permitted use have not been established—not that a web page can decide the repair.

What's the difference between a dock seal and a dock shelter?

A compression seal uses foam pads the trailer backs against. A shelter uses curtains around the trailer’s sides and top, often accommodating a different range of trailer sizes. The products have different fit and mounting requirements, so a provider should identify the assembly before pricing repair.
