This 17x17 mm inner fixing end with a height of 37 mm is perfectly suited for a square tube with a 20 mm outer diameter and 1.5 mm thickness.
Thanks to its 8 mm internal thread, it will allow you to mount casters with an eye (with a central hole) of 8 mm diameter in your tube. In this regard, it is equipped with 2 nuts inside, the upper one being a locking nut, which ensures exceptional durability over time, far superior to standard sockets.
To fix your eye caster, simply force this end into the support. Once the sleeve is in place, you will just need to screw your caster using a corresponding diameter bolt.
The end is made of black polyamide 6 and the nuts are made of steel.
Compatible with a threaded rod or bolt of at least 42 mm in length.
