SKU: N/A Category: Tag:

The Mad Rock Hulk HMS Screw Gate is ideally suited for use with canyoning descenders where the rope runs directly across the surface of the carabiner.

The hot forged construction not only reduces weight while maintaining an extremely high rated breaking strength, it results in one of the most affordable HMS carabiner on the market.

The rounded top of the oval allows rope to run smoothly across the surface, with the even spread of friction preventing the formation of sharp edges and delivering a longer life-span.

Fits a range of popular canyoning descenders, including the BG Gear SQWUREL, Imlay CRITR2, On Rope Hoodoo-SL, Sterling ATS, AustriAlpin No.Mad or Resonator 3000.
