Very precise and clean looking way to connect extrusion profiles at an angle. Comes with everything to install (as pictured in the product description). The quality is good with an even black finish. Five stars from me. I hope this helps to make a decision.

Très bon produit, très jolie. Je recocommande.

Whether you get this painted silver or black, (note identical tooling marks), the unknowns are:1. strength of zinc alloy vs. extruded high-grade aluminum2. quality of paintBut for the price, there's not much of an alternative. Just be aware and don't ask more of this fitting than is safe.

Je m'en sers pour faire des assemblages sur mes profilés de Sim Racing. Très fidèle à l'original que j'avais avec Trak Racer mais goupilles de réglages en plus. Bon produit.
