Petzl Delta Screw Link

The Delta is a triangular steel quick link designed for semi-permanent connections in rigging and hardware setups. Unlike a standard carabiner, it is meant to be closed with a wrench, making it ideal for applications where you need a secure, fixed connection point.

You should select the 8 mm version that specifically includes the positioning bar. This bar is designed to keep your CROLL ascender properly oriented on your harness, preventing it from flipping or shifting during use.

Yes, the 10 mm version is significantly stronger, offering a major axis strength of 45 kN compared to the 27 kN rating of the 8 mm version. Choose the 10 mm link if your rigging application requires higher load-bearing capacity.

While the Delta is built from durable steel and meets safety certifications for rigging, it is primarily intended for hardware and equipment connection. Always verify that the specific link you choose meets the safety standards required for your particular activity or industry.

No, the black finish is purely aesthetic and does not compromise the steel construction or the strength ratings of the link. It is a great option if you need a more discreet, low-profile setup for tactical or specialized work environments.
