Enclosed Conveyor Belt Tensioners
Prevent debris buildup, and thread damage—these tensioners have a totally enclosed adjusting screw. Tensioners mount to the sides of the conveyor and attach to the bearings that hold the pulley. Note: Two tensioners and two base-mount bearings (not included) are required.
Stainless steel tensioners are corrosion resistant.
