Available in steel, aluminum alloy 3003 and stainless steel Type 304. Splice-Locks are designed for the alignment of handrail sections and as expansion joints. They are most effective as a joint stiffener when used within 12″ of a welded post or handrail bracket.

The screw hole is threaded into the connector and theSingle-Lock Splice-Lock’s prongs hold the piece together as a unit allowing for simple insertion into the pipe or tube. The set screw is a headless socket with a cup end.

Splice-Lock tube and pipe connectors have a similar shear strength as standard pipe but are not to be used in post Assemblies.

Splice-Lock tube and pipe connectors are available in single-lock and double-lock.

Single-Lock Splice-Locks are for use as Connectors or expansion joints. For maximum strength, use Double-Lock Splice-Locks.
