Strong, malleable iron, slip-on pipe fittings with from one to five case-hardened
set screws per fitting – depending on the number of pipes to be joined at one joint.
For slip-on aluminum fittings. These fittings can support an axial load of 2000 lbs
per set screw with the set screw tightened to a torque of 29 lbs/ft. This is normally
obtained when the screw is fully tightened using a ratchet wrench.

This fitting, with holes provided for countersunk flat head screw fixings only, is designed to carry handrails along walls or to fix structures back to walls. The pipe passes through the fitting and cannot be joined within the fitting. Type 70 is also used to attach toeboards to the base of guardrail uprights.
Warning: These fittings are not to be used as base flanges for full height guardrails.
