Ancon® Lockable Dowel

InfraBuild Reinforcing supplies Ancon® Lockable Dowels, which are designed for use in temporary movement joints. They allow initial shrinkage of the concrete to take place and are then locked in position, by mechanical and chemical means, to prevent further movement taking place.

Ancon® Lockable Dowels eliminate the need for complicated formwork and are ideal for slab-to-slab and slab-to-wall connections in a variety of steel reinforcement applications.

Ancon® lockable dowels from InfraBuild Reinforcing are available as:

  • ESDQL20 for Slab-to-Slab applications
  • HLDQL30 for Slab-to-Slab applications with high loads
  • ESDQL20W  for Slab-to-Wall applications.

The complete dowel set comprises the dowel itself, the sleeve including the lid, the locking plate, and a 2-part epoxy resin.
