A full lineup of dock bumper models—sizes, profiles, and materials for every bay
Wrong Spec, Real Cost
Use the quick steps below to dial in your loading dock needs.
Step 1: Match Your Type
Slide-Effect: All-Around Bumper Solution
- Engineered for sloped approaches, built for heavy traffic.
- Inset aluminum track + spring that allows the bumper to move with the trailer
- Easy, tool-free bumper replacement and lifetime mounting plate warranty
Steel-Faced: Toughest Protection on the Market
- Withstands the heaviest hits and highest volume
- Steel face allows the trailer to ‘glide’ while the rubber absorbs the impact
- Fewer replacements lead to lower lifetime cost – backed by 5yr warranty
Laminated: Best Value for Everyday Bays
- Cost effective solution for medium traffic bays
- Resilient, recycled-rubber laminations that protect the dock and trailer
- Easy install with largest lineup of options
Molded: Budget Option for Light Traffic
- Ideal for light-duty bays that still need dependable protection
- Pre-drilled, countersunk holes make mounting easy
- High rebound rubber resists permanent compression
Step 2: Calculate Projection
What it is: how far the bumper sticks out from the wall.
Goal: Keep trailers and leveler lip from hitting the building as the trailer “floats” up or down
Rule of thumb
Projection ≈ %grade + 5 in
Quick Guide
| % Driveway Grade | Projection |
| 0% (flat) | 4-5 in |
| 1% | 6 in |
| 2% | 7 – 8 in |
| 3% | 8 – 9 in |
| 4% | 9 – 10 in |
| 5% | 10 -11 in |
| 6+% | 12+ in |

Step 3: Orientation & Face Size
Horizontal Bumper
- Approach is flat or slight grade (0 – 2%)
- Fleet height and/ or wear mark is consistent
- Vertical travel is controlled or negligible during unloading
Common Sizes
- 12″ x 18″ – Everyday standard size
- 10″ x 24″ – When re-spotting is a problem and height isn’t
- 12″ x 36″ – Heavy duty, maximum coverage
Vertical Bumper
- Approach grade is significant (≥ 3%)
- Fleet height varies
- Big vertical travel when unloading
Common Sizes
- 20″ x 11″ – Standard size
- 24″ x 11″ – More coverage for increased grade or travel
- 36″ x 11″ – maximum coverage
Step 4: Installation Style
Standard Bolted
- Fastest installation and most familiar retrofit style
- Works in leased facilities or when welding is available
- Best when both sides have good concrete to anchor to
P1 (One Weld Plate)
- One side has steel curb, other has good concrete
- Damaged/obstructed concrete on one side
- Requires Hot Work!
P2 (Two Weld Plates)
- Both sides have curb angles or embedded steel to weld to
- Maximum rigidity & durability for high-cycle, high-abuse docks
- Cleanest install for new pits – minimal drilling maintenance later
P1L / P1R (Slide Effect Only)
- Left and Right application styles for Slide Effect Bumpers
- Must have both left and right to preserve the built-in approach angle
Learn Which Style Fits Your Dock
Before ordering, take a close look at your loading dock pit construction. The way your pit is built determines which bumper installation style will work best. Use the guide below to match your dock pit with the correct option.
Steel Curb and Concrete Walls
If your dock pit has a single steel curb/angle to weld to with concrete surrounding it, you’ll want a bumper that can fasten securely to both materials.
- P1 (One Welded Side, One Bolted Side): Weld to the curb for strength and bolt into the concrete wall for stability.
- Standard (Two Bolted Sides): Bolt directly into the concrete if welding isn’t required.
Full Steel Face Plate
If your dock pit is built with a sheet of steel covering the entire face (no exposed concrete to bolt into), welding is the only secure installation method.
- P2 (Two Welded Sides): Both sides of the bumper weld directly to the steel plate, ensuring a solid and long-lasting hold.
Other Dock Pit Types
Not all loading docks are the same. If your pit doesn’t look like the examples above, don’t worry — we can help.
