Halfen HSD-LD 20 Lockable Dowel

A Lockable Dowel allows initial shrinkage of the concrete to take place and then, after a predetermined time period (generally 30 to 90 days), is locked in position with a mechanical plate and a controlled amount of epoxy resin.

The dowel component is manufactured from 1-3/16″ diameter stainless steel; one end is threaded with a fixed nut and washer, and the other features a series of grooves to accept a Locking Plate. The cylindrical sleeve which accepts the dowel component is contained within a box-section to allow lateral, longitudinal, and rotational movement. The epoxy resin is poured into the L-shaped void former.

This product has a maximum design shear strength of over 15 kip.
