Fittings for GRP handrails are supplied as two identical halves which simply clamp together around the tubing. These need to be drilled onsite using a standard 9mm diameter HSS drill bit (supplied with your order) and bolted together with the special stainless steel rivnut fixings provided.
The bolts are then inserted and tightened using a pozi 3 driver, the knurled rivnut fixing will hold in place whilst the bolt is tightened. These fixings provide a flush finish with no protruding bolt heads.
GRP handrail fittings are supplied as one-piece construction, can be glued onto the tubing using special rapid-set PU adhesive.
