These blocks were used on a heavy-duty soundproofing curtain pulley system.

I bought these cheek blocks to rig up a pully operated auto shut off for my Tritoon Lift. They are ball bearing (nylon) and will fit up to a 5/16" line. The mounting strap is stainless and mounts with two 1/8" to 3/16" screws.

The bearingless all stainless pulleys are not worth it. Buy this.

Light weight. But should work for light duty.
