Replacement chain idler sprocket for Allstar, Allister and Raynor garage door openers. Since the 6100002 Raynor, 100004 Allister and 009145 Allstar 15-tooth sprockets have been discontinued the 112045 Idler Pulley makes an excellent replacement. The sprocket can be replaced with a pulley since this is not a drive sprocket but an idler sprocket and the teeth are unnecessary. The idler pulley allows the chain to travel along the rail and keeps the chain in line with the drive sprocket attached to the top of the powerhead.
A good replacement for the discontinued original 6100002 Raynor 15-tooth sprocket that was used as a front idler sprocket on the Flitestar garage door opener & R-Series garage door operator models.
