Filler-Lok is a patented two part, non-foam polyurethane product that is used to fill holes in timber, composite and concrete sleepers. It is proven to retain screws and spikes better and longer than other traditional plugging materials.
Filler-Lok is used on conjunction with Cold Forge's SlabLok sleeper repair system, and is an excellent complement to our GageLok screw range when re-sleepering.
Filler-Lok bonds so tightly to the spike hole surface that it will not dislodge during the adzing process. Unaffected by water, Filler-Lok completely displaces standing water in used holes without excess foaming, and it deeply penetrates cracks, voids and crevices in the sleeper to reduce moisture infiltration and sleeper rot.
Filler-Lok helps maintenance crews be more efficient by allowing them to re-fasten more rails in less time and providing a product that lasts longer than any alternative. Filler-Lok will provide an immediate return on investment by reducing tie maintenance costs and rail down time.
