The aligner bracket mounts to most manufacturers’ self-aligning idlers, allowing for broad application. To improve safety, the design eliminates the need to tie off idlers to the surrounding structure, and the locking bar features a hole for padlock placement to restrict access and handle movement. The slotted comb on the new idler provides a range of incremental adjustment settings (±7.5˚) to ensure consistent performance. The handle can also be allowed to float freely on top of the locking bar to provide course adjustments of ±2.5˚.
