Use with Ref 70 bolts in heavy duty applications.
Is the installation of Ref70 bolts any different to other elevator bolts?
When using the large Reference 70™ (REF 70™) oval washer with the REF 70™ bolt, the washer should be placed with the widest part across the belt in order to minimize stress on the system as it passes around the curved pulley.
Note: the bolt head and oval washer are installed on the back of the belt.
