Details...
- matched double-bend side
plates help eliminate compression under load
- Solid side plates help to
keep dirt and debris out of the rope track
- Oilite bearings are popular
for delivering reliable performance at a reduced cost
- sealed ball bearings provide
optimal efficiency
- sealed ball bearings are not
prone to failure under misaligned loads or with twisted gear as can be
the case with needle bearings
- axle-nuts are double locked
to the steel axle and marked with a witness line in order to help
detect any loosening
- attachment hole is sized to
accept large rescue carabiners with sufficient room to allow the
carabiner to rotate freely and easily
