Which piece of dock equipment is it?
Most of what sits around a dock opening has a specific name, and using it saves a phone call. Here is what each piece is and what it does.
| What it looks like | What it's called | What it does |
|---|---|---|
| Fabric pads around the opening that the trailer presses into when it backs up | Dock seal | Closes the gap between the trailer and the building |
| A fabric or rigid hood the trailer backs under, with curtains hanging down | Dock shelter | Same job, more clearance, suits mixed trailer heights |
| Rubber blocks bolted to the face of the dock | Dock bumpers | Take the impact so the building, the door and the leveler don't |
| A loose metal plate somebody sets down across the gap | Dock plate or dock board | Portable bridge between the floor and the trailer bed |
| An arm-mounted light that swings into the trailer | Dock light | Lets somebody see inside the trailer |
| A wedge placed behind a trailer wheel | Wheel chock | Helps keep the trailer from moving |
| A steel platform set in a pit at the dock edge | Dock leveler | Not this page — dock leveler repair |
| A powered hook or arm that grabs the trailer, with red and green lights | Vehicle or trailer restraint | Not this page — trailer and vehicle restraint repair |

Dock plates and dock boards
A dock plate or dock board is a portable bridge. Somebody lays it across the gap between the dock floor and the trailer bed, and picks it up again afterwards. It is not the same equipment as an installed dock leveler, and the industry standards keep them apart: ANSI MH30.1 covers dock leveling devices, ANSI MH30.2 covers portable dock leveling devices, and ANSI MH30.3 covers vehicle restraining devices.
The rule that matters most is a safety one, and there is no polite way to soften it. Never assume a bent, cracked or damaged portable plate or board can be welded, straightened, or put back into service. Do not let a forklift onto one. Take it out of use through your facility's established process and have it assessed. A plate that fails under a loaded truck is one of the worst things that can happen at a dock.
What the federal rule actually requires of dockboards is worth knowing, because it tells you what a provider is checking for. Under 29 CFR 1910.26, employers must ensure that dockboards are capable of supporting the maximum intended load; that dockboards put into initial service on or after January 17, 2017 are designed, constructed and maintained to prevent transfer vehicles running off the edge, with a stated exception where the employer can demonstrate there is no such hazard; that portable dockboards are secured against moving out of a safe position; that measures such as wheel chocks or sand shoes prevent the transport vehicle from moving while employees are on the dockboard; and that portable dockboards have handholds or another means for safe handling.
Two things people repeat that are not in the standard. There is no run-to-rise or slope ratio anywhere in 29 CFR 1910.26. And 29 CFR 1910.178(j) is now only a cross-reference — its full text reads "Dockboards (bridge plates.) See subpart D of this part." It sets no capacity or marking requirement, so a claim sourced to it is not a claim about current federal text.
What to report on the call: which bay, whether it is bent, cracked, or has damaged legs, curbs or handholds, roughly what it weighs or how big it is if you know, and whether anyone has been driving on it.
Dock seals and dock shelters
A seal and a shelter do the same job in different ways. A seal is made of foam pads covered in fabric, mounted around the opening; the trailer reverses into it and compresses it. A shelter is a hood or frame with curtains, and the trailer backs under it rather than into it. Seals close tighter but need trailer sizes to be fairly consistent. Shelters handle a mixed trailer fleet and allow the doors to open fully inside the opening.
What failure looks like. On a seal: torn or split fabric, foam that stays crushed instead of springing back, pads pulling away from the mounting, and a visible gap when a trailer is docked. On a shelter: torn head curtain, bent or damaged frame, side curtains ripped off their fasteners, and the same visible gap.
Why it is worth fixing rather than living with. A failed seal or shelter means conditioned air going out, weather and pests coming in, and at a refrigerated opening it becomes a product question rather than a comfort one. It also means whatever is blowing through is hitting the door and the leveler every day.
What to report on the call: which bay, whether it is a seal or a hood, what is torn or missing, and whether the frame took an impact.
Dock bumpers
The bumper is the part that is supposed to take the hit. When it is gone, the trailer starts hitting the building, and then the door, and then the leveler.
Bumpers are done when they are compressed flat, split, torn away from their mounting, or simply missing. Laminated bumpers are built from rubber pads stacked on a steel frame. Steel-face bumpers add a plate on the front. Either way, once the rubber is through, the hardware and the concrete behind it become the next thing to fail.
A boundary worth naming: if the concrete the bumper is bolted to has broken up, that is a concrete and structural question, not a bumper one. A provider can tell you which you are looking at.
What to report on the call: which bay, whether the bumper is missing or just worn down, and whether the concrete behind it looks damaged.
Dock lights, chocks and accessories
Dock lights are the arm-mounted lights that swing into a trailer so somebody can see what they are doing. They fail in ordinary ways — the arm seizes, the head breaks, the cord goes, the switch stops working — and the electrical side is regulated work.
Wheel chocks are a securement item rather than a repaired one, but they belong in this conversation because the federal rule ties them to the dock. Under 29 CFR 1910.178(m)(7), "Brakes shall be set and wheel blocks shall be in place to prevent movement of trucks, trailers, or railroad cars while loading or unloading," with fixed jacks where a semitrailer is not coupled to a tractor, and the flooring checked before driving onto it. That is an employer duty about how the dock is operated, not something a repair company sets for you — but it is why a missing chock is worth replacing right away.

An example of what that first sentence can sound like: "The dock seal on bay 12 is torn off one side at our facility in Boston, and I can give you the address." That is example wording, not a script and not a real job.
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
Say which bay and what's damaged.
Useful to have — but not required
You can call without any of this. The facility address, the bay number and "the seal is torn" are enough.
If you already know them: how many bays are affected, roughly how old the equipment is, whether the trailers that use that bay are a consistent size, and whether anything hit it recently.
Do not go and look. Nobody should climb on a dock face, reach around a raised leveler, or get between a trailer and the building to measure anything.
What decides what this costs
We can't quote dock equipment work from a web page. The price depends on which piece it is, the size, the parts, and access. Here's what to ask before you authorize work.
| What changes the price | What to ask |
|---|---|
| Call-out or diagnostic fee | "Is there a call-out fee, and does it come off the work?" |
| Which piece, and how many bays | "Is this priced per bay or per visit?" |
| Seal or shelter size, and the trailer mix using that bay | "Is the size being confirmed on site before the order?" |
| Repair versus replacement of the unit | "Is this a repair, or a new seal or shelter?" |
| Mounting hardware and condition of the substrate | "Is the mounting in scope, and what if the concrete is damaged?" |
| Parts availability for the make | "Are parts current, or is this a full replacement?" |
| Access and whether the bay stays in production | "Does the bay need to be out of use, and for how long?" |
Ask which kind of number you are getting: a call-out fee, a starting price, a scoped fixed price, an estimate, or a final quote.
Ask the price questions on the phone.
Massachusetts rules worth knowing before you authorize work
Massachusetts does not license dock equipment work as a trade. There is no board for it. The Construction Supervisor License attaches to supervising work regulated by the state building code, and regulated electrical work — dock lights, powered accessories, controls — sits with the Board of State Examiners of Electricians. Ask which credential covers the scope being proposed, and check it: the Construction Supervisor lookup and the electrician lookup are two different systems. Massachusetts adopted the 2026 National Electrical Code effective April 24, 2026.
If the work touches the building structure or the dock face, ask the building official which permit path applies. In Massachusetts that is your city or town, never the county. Boston's Inspectional Services Department publishes 617-635-5300 and isd@boston.gov. The provider and the issuing office confirm what applies to your job.

Common questions
What's the difference between a dock seal and a dock shelter? A seal is foam pads the trailer compresses against. A shelter is a hood with curtains the trailer backs under. Seals close tighter and suit a consistent trailer size; shelters handle a mixed fleet and let the trailer doors open fully inside the opening.
Does the bumper really matter? Yes. The bumper is the only thing standing between a reversing trailer and your building, your door and your leveler. A missing bumper is not a cosmetic problem — it is the reason the next repair is more expensive.
Can a bent dock plate be repaired? Do not assume so. Take it out of use through your facility's process and have it assessed. Nobody should weld, straighten or return a damaged portable plate to service on a judgement call, and nothing should be driven onto it in the meantime.
Do you cover dock levelers on this page? No. Installed levelers — including edge-of-dock units — have their own page. Dock leveler repair is here.
