Identify this pulley variety??

Not hammock related, but I figure many on this forum will know the answer. Can anybody identify the type/category/name of the pulley in the attached photo?pulley.PNG
The pulley in the photo is one piece of a multi-part hoist system for hanging kayaks on garage rafters. I have several small, light-weight items I would like to hang from my garage rafters -- only 5 pounds or so each. I don't want to buy the entire kayak hanging system just to get one of these pulleys with the built in bale that locks the rope when you pull the rope at an angle. I have searched all over Google using terms like locking pulley, pulley with rope brake, etc. and I cannot seem to find this type of pulley without buying the multi-piece kayak hanging system. The advantage of this system to me is that unlike with a regular pulley, I would not need to tie off the rope after hoisting the item. I could just use the built-in rope brake mechanism. Any suggestions on the technical name for this type of pulley so I can search for it more accurately?

Maybe a 'locking rope hoist' or 'hoist with brake'. That particular design looks like it is used for both bikes and kayaks, but there may be other designs that do the same thing. Home Depot appears to have a version for bikes with two of the pulley's for ~$15, sold as a 'CargoLoc Ceiling Mount Bike Lift'.

Nite-ize makes both plastic and aluminum cams that you might incorporate in a DIY solution. See their other types of cord tighteners, too. For 5 lb. loads you might not need a pulley.
