Good morning everyone, Im a rookie arborist here, topped my first tree a few days ago, was in the corp of engineers for a while and did some tree climbing there. im looking to do some design work and machining of tools that may help. Ive designed this tool as a friction system to aid in lowering trees down, or as an anchor point for multiple tie offs, any suggestions or feedback on this?

its for 4x holes that are all 1.5in dia with large radii lead ins, overall its 8" long and 5.5" wide and 1.25" thick, and weighs 2.1lbs

I do alot of my work alone, im not part of a crew or anything, mostly working at home, so If I top a tree I wanted something I could manage lowering it down myself (im sure its super dangerous since I should be focused on not falling out of the tree) but I wanted something to help with the safety aspect.

let me know what you think.

Did you design that from scratch?
I ask because it looks similar to the Notch Triple Thimble or the Safebloc.

Having used neither, (only seen them in a few videos) I'm curious if you had improvements in mind when designing yours vs. those.
