20mm Plain Bearing Blocks

Allen 20mm plain bearing blocks offer good static loading capabilities at a low weight and cost. The ideal choice for systems which are not fast running or need constant adjustment. Made using recycled materials and featuring a grey sheave to differentiate it from the dynamic block range.


Plain Bearing – Recycled plastic sheave which spins around a stainless steel axle.


Ultra-Strap – A stainless steel strap which holds the block together and provides a strong, reliable and rope friendly attachment point.


Becket – The hole through the middle of the block can be used as a tying off point (becket).


Breaking Load – The load at which a major block failure is likely to occur.
