Overview
The pull chain opening on a dock leveler is one of the most overlooked entry points for mice, rats, and other rodents at commercial loading docks. The chain itself acts as a built-in ladder, and the opening is typically large enough for rodents to pass through and access the interior of a facility. The Xcluder RodentBLOCK pull chain seal from Action Industries is a purpose-built solution that completely covers the chain access hole, creating a physical barrier that blocks pest entry without affecting normal dock leveler operation.
Constructed from solid cast aluminum, this pull chain seal is engineered for long-term performance in demanding dock environments. It installs quickly over the existing chain opening and sits completely below the surface of the dock plate, so forklifts, pallet jacks, and other material handling equipment can operate without obstruction. For facilities that need to reduce or eliminate reliance on chemical pest control, this seal provides a practical, non-toxic line of defense at a commonly exploited vulnerability.
Features and Construction
The RodentBLOCK pull chain seal is made from solid cast aluminum — a material chosen for its strength, corrosion resistance, and durability under repeated exposure to moisture, temperature changes, and heavy dock traffic. Unlike thin plastic or sheet metal alternatives, the rigid aluminum body holds its shape and continues to perform over time without warping or degrading.
The seal is available in three sizes to match common pull chain hole diameters found across dock leveler brands and models. The low-profile design ensures a flush fit below the dock plate surface, maintaining a smooth, uninterrupted plane that does not catch equipment wheels or interfere with material handling. Installation requires no special tools or modifications to the leveler — the seal simply covers the chain opening and stays in place, providing immediate rodent exclusion from the moment it is installed. Manufactured in the USA, the pull chain seal reflects Action Industries’ commitment to quality construction in every component of their Xcluder pest exclusion product line.
Applications and Environments
This pull chain rodent seal is designed for any commercial or industrial facility where pest exclusion at the loading dock is a priority. It is especially well suited for environments where maintaining a pest-free operation is critical to food safety compliance, audit readiness, or integrated pest management programs. Common applications include food processing plants, cold storage and warehouse facilities, food distribution centers, grocery stores, pet stores, and supercenters.
The seal works as part of a broader dock-level exclusion strategy. When combined with Xcluder RodentBLOCK dock leveler seal kits, door bottom seals, and passage door sweeps, it helps close every potential rodent entry point across the loading dock — reducing the need for traps, baits, and chemical treatments while supporting a cleaner, more compliant facility.
Available Sizes
The RodentBLOCK pull chain seal is offered in three standard sizes based on the diameter of the pull chain hole on the dock leveler. Measuring the existing opening before ordering ensures a correct, secure fit.
- 1-3/4 inch pull chain hole diameter — Item No. 106-0004
- 2 inch pull chain hole diameter — Item No. 106-0005
- 2-1/2 inch pull chain hole diameter — Item No. 106-0006
If you are unsure which size fits your leveler, Barron Equipment can help you identify the correct pull chain seal based on your dock leveler make and model.
Selection Assistance
Choosing the right rodent exclusion products for your loading dock depends on the number of levelers, the types of openings present, and the level of pest pressure your facility experiences. The pull chain seal addresses one specific — but commonly missed — entry point. For full dock-level protection, consider pairing it with a RodentBLOCK dock leveler seal kit and Xcluder door bottom seals across all dock and access doors.
