The Fixe Triplex bolt was designed specifically for rock climbing. Triplex is the highest quality climbing bolt available. Triplex uses the same expansion principal as the Rawl 5-Piece bolt. Triplex takes anchoring a step further by eliminating the nose cone with a solid stud system. This design allows Easy Removal for replacement and consists of only 3 Parts. The sleeves expand by tightening the nut which draws the tapered stud from the hole. This system places the threads outside of the rock eliminating hidden thread and nose cone corrosion. The Stainless Steel model is suited for the most corrosive limestone. Triplex can be easily inspected for corrosion by quickly removing the entire unit. This bolt can be used in soft and pocketed rock. Triplex can also be utilized to equip a Glue-In anchor using the same hole size for both bolts. Triplex bolts are reusable!
