SKU: N/A Category: Tag:

The Mad Rock Hulk HMS Screw Gate is a style of carabiner designed specifically for use with descenders where the rope runs directly across the surface of the ‘biner.

The hot forged construction of the Hulk not only allows weight to be reduced while maintaining an extremely high rated breaking load, it also delivers one of the most affordable HMS carabiner on the market.

By ensuring the top of the oval is rounded, the rope can run smoothly across the surface. The more even spread of friction prevents the formation of sharp edges and delivers a longer life-span.

Fits a range of canyoning descenders, including the AustriAlpin No.Mad, BG Gear SQWUREL, and Resonator 3000.
