A machined Tylaska ring for low-friction rigging points and redirects.
The Tylaska DTR20 arborist rigging ring is a machined ring from a maker known for marine and rigging hardware, used by tree crews as a low-friction rigging point or redirect. Rope runs smoothly over its rounded profile, with no moving parts to wear out.
A rigging ring sits in a sling at the rigging point and gives the line a smooth, rounded surface to run over. It is simpler than a block, with no sheave or bearings, and it adds a bit of friction that can help a ground worker control lighter loads.
Crews also use rings as redirects and as connection points in soft anchors. Browse our rings and rigging hardware for related gear.
Because there are no moving parts, a ring is simple to set and hard to break. It lives easily on the saddle or in a sling, and it is a good choice for jobs where a block would be more than you need.
Check the maker's rating and rope range and keep loads well within them. A rigging point can see close to double the line load, so plan for it.
Before each use, look for grooves worn by the rope, cracks, sharp edges, and deformation. Retire the ring if it has taken a severe shock load. Rigging should follow ANSI Z133.
Store it clean and dry, and retire it after a drop from height onto a hard surface unless the maker says otherwise.

A ring is simpler and adds friction. A block has less friction and suits heavier, faster loads.
