Overview
Action Industries molded rubber dock bumpers provide impact protection for loading docks using a solid, one-piece rubber construction rather than the layered recycled-tire design found in laminated bumpers. Molded bumpers are manufactured by forming reinforced rubber into a single solid shape, creating a dense, uniform structure that absorbs trailer impact and protects dock faces, dock levelers, and building walls from collision damage.
Barron Equipment carries the full Action Industries molded dock bumper lineup in seven configurations, with heights ranging from 13 inches to 30 inches and widths from 10 to 18 inches. All models feature a standard 4-inch depth and are designed for straightforward bolt-on installation at commercial loading docks.
Construction and Material
Unlike laminated dock bumpers — which are built from compressed layers of recycled tire material held together with steel rods — molded bumpers are formed from reinforced rubber in a single manufacturing process. This creates a uniform, solid body with no internal layers, seams, or steel rods. The result is a bumper with consistent density and impact resistance across its entire surface.
The solid rubber construction is naturally resistant to weather, UV exposure, oils, and temperature extremes. Molded bumpers will not delaminate because there are no layers to separate, making them a dependable choice for facilities that prefer a simpler construction with fewer internal components. Mounting bolt holes are pre-formed into each bumper for direct attachment to the dock face.
Available Sizes
Action Industries molded dock bumpers are available in the following configurations. All models feature a standard 4-inch depth (projection).
- L1310-04-Z — 13″H x 10″W x 4″D | DB-13 style, 2 bolt holes | 20.8 lbs
- L1312-04US-Z — 13″H x 12″W x 4″D | Made in USA | 25 lbs
- L1312-04-Z — 13″H x 12″W x 4″D | Type R, 4 bolt holes | 25 lbs
- L1810-04-Z — 18″H x 10″W x 4″D | Tall profile | 28.8 lbs
- L1818-04-Z — 18″H x 18″W x 4″D | Wide and tall profile | 51.8 lbs
- L2410-04-Z — 24″H x 10″W x 4″D | Extra-tall vertical profile | 38.4 lbs
- L23010-04-Z — 30″H x 10″W x 4″D | Tallest molded profile | 48 lbs
Two models share the same 13″H x 12″W footprint but differ in construction type and bolt pattern. The L1312-04US-Z is manufactured in the USA, while the L1312-04-Z features a Type R construction with four bolt holes. Confirm which configuration matches your dock mounting requirements before ordering.
Molded vs. Laminated Dock Bumpers
Both molded and laminated dock bumpers protect loading docks from trailer impact, but they differ in construction, cost, and best-use applications.
Laminated bumpers are constructed from compressed layers of recycled truck tires reinforced with steel rods. They are available in a wider range of sizes and projections — up to 12 inches deep — and are the most common choice for heavy-traffic commercial docks receiving standard semi-trailers. Their layered construction provides high impact absorption and long service life under demanding conditions.
Molded bumpers use a solid, one-piece rubber body with no internal layers or steel reinforcement. They are typically more economical than laminated bumpers and are well suited for light to moderate traffic docks where straightforward impact protection is the primary requirement. Their uniform construction means there is no risk of delamination over time, and their clean appearance makes them a popular choice for customer-facing or retail receiving areas. However, the standard 4-inch depth offers less projection than the 6-inch to 12-inch options available in the laminated and steel face lines.
For docks receiving air-ride trailers or experiencing significant vertical friction, neither standard molded nor standard laminated bumpers are the best choice — steel face dock bumpers are recommended for those applications.
Applications
Molded rubber dock bumpers are commonly installed at loading docks operating at light to moderate traffic levels where cost-effective impact protection is the priority. Typical installations include retail store receiving docks, small warehouse shipping bays, office building service entrances, restaurant and food service delivery docks, and light commercial facilities with occasional trailer traffic.
The taller models in this lineup — the 24-inch and 30-inch configurations — provide extended vertical coverage for docks where trailer contact occurs across a wider range of heights, or for facilities that want full-height protection across the dock face without stacking multiple smaller bumpers.
These bumpers also work well as supplemental protection in non-dock applications such as parking garage walls, building corners exposed to vehicle traffic, and interior warehouse walls near forklift travel lanes.
Selection Assistance
Choosing the right molded dock bumper starts with measuring the height and width of the area on your dock face that needs protection. Match those measurements to the closest available bumper size. All models in this lineup have a fixed 4-inch depth, so if your dock requires more stand-off distance between the dock face and the trailer, consider an Action Industries laminated dock bumper with 6-inch to 12-inch projection options instead.
Pay attention to bolt hole configuration. The DB-13 style (L1310-04-Z) has 2 bolt holes, while the Type R (L1312-04-Z) has 4 bolt holes. If you are replacing an existing bumper, match the bolt count and pattern to avoid re-drilling your dock face.
For light to moderate traffic docks receiving conventional trailers, molded bumpers provide reliable protection at a lower cost per unit. For heavy-traffic facilities, docks receiving air-ride trailers, or applications requiring greater projection, laminated or steel face bumpers from Action Industries are the better fit.
