T-Cycle Double Sided Clamp On Chain Keeper
The Clamp-On Double-Sided Chain Keeper is designed to maintain your chain on an Over/Under Idler. The double-sided and single-sided Clamp-On Chain Keepers are TerraCycle exclusive products. Nowhere else will you find a chain keeper that clamps onto the head of an idler bolt. Clamping on means freedom to float your chain keeper side to side with the chain and the idler, and it means super easy setup and maintenance. The abrasion resistant nylon arm, stainless steel fasteners and high quality machined aluminum means your Clamp-On Double-Sided Chain Keeper will be with you a long time.
These clamp on chainkeepers were developed to enable idler float and to make everyone's lives simpler. Since the chainkeeper attaches itself to the head of the idler bolt, it is completely independent of everything else. That means the idler bolt can be tightened without squeezing the idler or chainkeeper. This allows the idler to float side to side with the chain for better efficiency. Also, since this chainkeeper clamps itself on, you don't have to put it on until everything else is done- very handy for maintenance. Install the idler and any spacers needed to keep it from rubbing on things and tighten the idler bolt. Lay in the chains, and THEN install the chainkeeper. How easy is that?
- The chainkeeper is machined with a clamp sized for the head of an 8mm Socket Head Cap Screw (the standard idler bolt). Super abrasion resistant nylon arms, with 5mm stainless bolt all the way through them, keep the chains from getting any ideas of going places they shouldn't. To install the chainkeeper, simply slide it onto the head of the 8mm bolt and tighten.
- 6061T6 aluminum, CNC machined and black anodized. MDS Nylon chainkeepers supported by M5 stainless bolts. Clamp designed for 8mm Socket Head Cap Screws with 0.52 inch (13mm) diameter heads. These chainkeepers can be used on other sizes of bolts, but larger bolt heads need to be turned down to 13mm and on smaller bolts or shafts a shim is needed to get up to 13mm.
