This fixing end cap is perfectly suited for a square tube of 40 mm per side and 2 mm thick.
Thanks to its internal thread of 12 mm, it will allow you to mount wheels with eye (with a central hole) of 12 mm diameter in your tube. For this purpose, it is equipped with 2 nuts inside, the upper one being a locking nut.
To attach your eye wheel, simply force this end cap into the support. Once the sleeve is in place, you will just need to screw your wheel in using a corresponding diameter bolt.
The end cap is made of black polyamide 6 and the nuts are made of steel.
Compatible with threaded rod or bolt of at least 42mm in length.
