The ERO Joint® HP (Hinge Pin) mechanical fastening system is available for H, T5, T10, AT5, AT10, T20, AT20, 8M, 14M, WT10 and WH pitches, for all widths from 10mm, with steel, Kevlar or stainless steel Reinforcement.
The mechanical strength of ERO Joint® HP belts is equivalent to welded belts.
Metal components are in stainless steel. No minimum diameter required. ERO Joint® HP can be used with all types of coating (Supergrip, Linatex, PU, Sylomer, etc.) and all types of drive guide.

Alternatives
Spiral joints
Mechanical spiral joints are as easy to assemble as an ERO Joint® HP joint, but their mechanical strength is very low.
Pin Joint
The Pin Joint mechanical jointing system is more difficult to assemble than an ERO Joint® HP joint.
Mechanical strength is also lower than an ERO Joint® HP joint.
