Rectangular Rubber HGV Bumper 425×120×100mm UK | Heavy Duty SBR Dock Protection

Extra-large heavy-duty SBR rubber dock bumpers for high-impact loading bay applications. The 425×120×100mm format combines a wide face area (425×120mm) with a generous 100mm rubber projection, making it the specification choice for busy distribution centres, large HGV fleets, and docks subject to frequent, high-energy reversing impacts.

Technical Specifications

Dimensions	425mm × 120mm × 100mm
Material	Heavy duty SBR rubber
Face Area	425mm × 120mm
Projection	100mm from wall face
Colour	Black
Rubber Grade	SBR (Styrene-Butadiene Rubber)
Free Delivery	UK mainland included

Performance Advantage

The 100mm SBR rubber projection compresses progressively under vehicle impact, slowing the approach rate and dissipating kinetic energy before the vehicle reaches the dock wall. This protects both the building structure and the trailer panels/curtains. The wide 425×120mm face accommodates height variation in vehicle sill heights across mixed fleets.

Key Benefits

Maximum energy absorption — 100mm SBR depth provides substantial rubber buffer for high-energy reversing
Wide face area — 425×120mm contact zone suits variable vehicle heights, reducing point loads on trailer panels
SBR durability — excellent abrasion resistance, oil resistance, and outdoor performance
Prevents structural damage — critical ROI benefit in high-traffic distribution environments
Reduces vehicle maintenance costs — protects trailer bodies from repeated dock contact damage

Installation Notes

Install at truck-bed height (typically 1.0–1.2m from dock floor for standard 40-tonne TIR trailers). Two bumpers per bay, one each side. Use M12 bolts minimum with chemical resin anchors in concrete. For high-frequency, high-impact docks, have fixings checked every 6 months.

Frequently Asked Questions

What is SBR rubber and why is it used for dock bumpers?
SBR (Styrene-Butadiene Rubber) offers excellent abrasion resistance, good energy absorption, and strong outdoor weathering performance at competitive cost — making it the industry standard for heavy-duty dock bumpers.

How do I choose between dock bumper sizes?
The 405×50×50mm suits light-contact and space-constrained docks. The 330×305×100mm is our general-purpose dock bumper. The 425×120×100mm (this product) is for high-frequency, high-mass HGV applications where maximum protection is needed.

Can I get a quote for fitting as well as supply?
We supply only — but dock bumper installation is straightforward and can be completed by a maintenance team or general contractor familiar with wall-fixing techniques.

Industrial-Grade Impact Protection for Loading Bays

The 425x120x100mm profile of this SBR dock bumper provides a wider contact face than standard bumpers, distributing impact energy across a larger area for improved protection of both vehicle and structure. The 100mm depth handles the high-energy impacts typical of articulated HGV docking.

Wide profile design — 425mm face distributes load across larger area than narrow profiles
Deep section — 100mm depth gives superior energy absorption capacity
High hardness SBR — 65–75 Shore A maintains shape under repeated heavy impact
Industrial specification — suitable for distribution centres, cold stores, factory docks
Simple installation — pre-drilled, fit directly to dock face with standard fixings
