Double-Lock Splice Lock™

View our how to Video For Wagner Splice-Lock™
DOUBLE-LOCK SPLICE LOCK™ Patented
Proven the best mechanical splice available for pipe and tubular railing field joints.

Splice-Locks are most effective as a joint stiffener when used within 12" of a welded post or handrail bracket.

Splice-Locks have a similar shear strength as standard pipe but are not to be used in post assemblies.

Numbers in Italics denote items that may not be available for
immediate shipment.

  1. Drill 13⁄32" diameter hole for 3⁄8" screws or 11⁄32" hole for 5⁄16" screws. This clear hole should be centered 3⁄8" from the end of each pipe or tube for 3-3⁄4" Splice-Locks™ or 17⁄32" to center for 6"and 8" Splice-Locks™, as shown.
  2. Insert Splice-Lock™ into this first section.
  3. Insert and partially tighten the set screw.
  4. Slide other section to be joined over the Splice-Lock™.
  5. Insert second set screw and tighten both screws fully.
Resultant action: Splice-Lock™ contacts inside of pipe or tube in four areas along the full length to ensure alignment and maximum strength.

Note: Both sections to be joined must have the same wall thickness.
