Polyurethane J-hooks and C-bars are a sawmill staple, with the plastic used usually being 75D hardness polyurethane. These hooks and c-bars are typically molded which means there is an upfront tooling cost; however, the per-part price is much lower than a machined part. Redwood Plastics and Rubber can manufacture whatever hook profile you need but there are other modifications to these hooks that can be done to suit customer’s needs. Firstly, a grit surface can be provided which increases the grip characteristics of the hook. LSI (steel later plates) are commonly embedded in the slider block at the top where the hook gets bolted in to provide reinforcement. In addition, the hooks can be manufactured out of SPS2000 which is kraftmill safe.
The colors of the hooks can also be customized (does not cost additional unless it’s a non-standard colour). Other potential additions include adding a screw for metal detectable properties or embedded lubricants.
