Proline connecting clips 5283900 for metal profiles up to 0.8 mm — fastening clips

Proline Profile Connecting Clips 5283900 are pliers designed for joining steel profiles with a maximum thickness of 0.8 mm. The punch and die are made from durable GR15 steel, while the head is constructed from an aluminum–titanium alloy (Al‑Ti) with a hardness of 57 HRC. The tool features a three-layer non-slip handle and has an overall length of 275 mm.

Advantages

Tool construction combines GR15 steel punch and die for wear resistance with an Al‑Ti alloy head for strength and reduced weight. A 57 HRC hardness rating ensures cutting and forming durability. The three-layer non-slip handle improves grip and control during use. The compact 275 mm length makes the pliers accessible in confined working areas.
