dock leveler kit aps resourcesThe APS ENERGYGUARD retrofit kit provides a perimeter seal along the sides and rear hinge of a dock leveler; blocks dirt, debris and pests; and prevents energy loss. A series of triangular-shaped side seal assemblies combined with a 2-ply rear hinge seal restrict mass airflow; the design seals the gaps between the dock leveler and concrete pit walls up to 9 in. above dock level. The kit has no mechanical components, springs, curtains or fabric.
