Rough-Top Slider Bed Conveyor Belting

The textured surface grips packages and cartons to prevent material from slipping when traveling on inclines and declines. A low-friction bottom surface allows belting to glide along the bed of the conveyor. Use belting with hammer-on hook-style lacing or quick-install hook-style lacing.

Note: The top surface of the belt ends should be removed with a conveyor belt shaver or skiver before installing lacing. Recommended lacing is based on the thickness of the belt after removing the top surface.

Black Neoprene

Neoprene has a good grip along with superior oil resistance.
