BOLT PULLEYS

Bolted Pulley Blocks use a bolt instead of a swivel eye, fixed eye or swivel hook to affix to your application, and are great for wire rope or cable pulley block systems.  Our 10 different Bolt Blocks (listed below) offer a more permanent solution, as it can be screwed into a surface or adhered by passing a bolt through the hole to the intended surface. Some of the most popular uses of Block Division’s bolt blocks are for the use of manufacturing animal feeders for field use, such as for deer and wild hog.  More specifically, it can be used to raise and lower the lid of the animal feeder.  In addition, bolt blocks are used to help raise and lower handicap ramps in specially equipped vehicles.

The long-term benefit is that zinc electroplating is a great material to use outdoors, especially for long-term, extreme weather conditions. Another highly popular use of our bolt blocks is for theater and stage use, such as the raising and lowering of massive theater curtains or draperies.

Note that 1.5” to 3” blocks must use 5/16” diameter bolt, and 3.5” to 5” block must use 1/2” diameter bolt.  After you choose the product size below, click "Order".  On the ordering page, you can request the length of bolt ("E") and specify NC (national course) or NF (national fine) thread callout.  To view product application photos, click here.  Questions?  Give us a call or send us an email.
