The polymer blocks are U-type attachments for roller chain designed to protect goods on conveying applications. With Renold's Klik-Top design, the blocks can be replaced in a matter of moments with a simple click-off and click-on action.
This is quite unlike integral attachments that can only be replaced by dismantling several chain components, which is quite a lengthy process.
