Solid Bushing Solid Roller (SBR)

Automatically all of our 81X chains are made with solid bushings and solid rollers because of the extremely prolonged working life and performance that comes from this design. So inherently our 81X rooftop chains will have the SBR feature.
Quad Staked Rivets

More often than realized 81X rooftop chain is put in circumstances where a side-load may be present or side-shock can happen. Because of this, we use a quad-staked rivet this doubles the side-load capacity of the chain.
