Prior to the introduction of PennLock, the only way to disconnect and re-connect chains was to use clumsy and cumbersome tooling which was not only time consuming but ran the risk of damaging the chain. This is why we developed Pennlock, this optional extra uses a threaded pin and a locking nut, meaning that Pennine’s PennLock can drastically reduce the time taken to join the chain, while also making the whole process much easier.
Side Guide chain has the guide links fitted to each side of the chain and the sprocket fits between them, keeping the chain aligned during operation. Side Guide chains are available in a variety of standard widths from 100mm (4 inch) up to 300mm (12 inch). Specials are also available on request, starting from 12mm (½ inch) wide.
Side Guide chains are available in Link and Spacer, All Link, Double Assembly and Special Assembly versions; please click on the relevant link on the left hand menu. In difficult applications Side Guide chains may prove to work more successfully compared with the Centre Guide option, where dirt could build up in the central groove preventing the chain from sitting correctly on the sprocket.
