Ancon Lockable Dowels have been designed for use at temporary movement joints. The dowel allows initial shrinkage of the concrete to take place and is then locked in position with a mechanical plate and a controlled amount of epoxy resin. The locked dowel continues to transfer shear, but prevents further movement taking place.

Ancon ESDQ-L20 Lockable Dowel
The ESDQ-L20 Lockable Dowel allows initial movement to take place and then, after a predetermined time period (generally 90-120 days), is locked with a two-part epoxy resin poured into the L-shaped grout box. This product has a design capacity of almost 70kN in shear and up to 100kN in tension.
Ancon HLDQ-L30 Lockable Dowel
The HLDQ-L30 is a high load Lockable Dowel with a design capacity of up to 136kN in shear and up to 100kN in tension.
Slab-to-Wall Lockable Dowel
Ancon ESDQ-L20W Lockable Dowel
The dowel component is manufactured from 30mm diameter Duplex stainless steel, but is shorter than the ESDQ-L20 dowel. One end of the dowel is designed to fix into the stainless steel Ancon SKS24 Threaded Anchor cast into the face of the concrete, and the other end features a series of grooves to accept the Locking Plate. The sleeve component is the same as used in the ESDQ-L20.
