ST 52 – Joint for “G” – “H” type profiles

ST 52 – Joint for “G” – “H” type profiles

GAMMA joints for G– and H-profiles are designed to ensure proper alignment of the bodies and to withstand loads.
ST-52-E – Joint for upper groove, G– and H-profile.
ST-52-F – Joint for lower groove, G-profile.
Using the ST-52-E joint, the position of the joint may correspond to the centre clamp tightening point. Therefore, it is recommended that G-profiles also be used with the ST-52-F profile. The joints are complete with self-tapping stainless steel VTEAs
