Changes to the Building Code Requirements for Masonry Construction require longer lap lengths for some bar sizes. These changes mean more congestion in masonry cells and more difficult construction. To alleviate this problem, builders can either use open-cell blocks, which are quite expensive, or use mechanical rebar couplers to eliminate the lap.

 

LENTONĀ® MASON LOCK is a taper-threaded coupler that quickly and easily connects two pieces of rebar. This cost-effective connector uses the time-tested, field-proven taper thread to help assure strength, consistency and reliability while simplifying installation. LENTON taper-threaded splices are designed for use on worldwide standard grades of rebar and meet ACIĀ®-318, BS 8110 and DIN 1045 full-tension splice requirements and many other international standards. LENTON couplers are available in sizes #3 - #18 (10 mm - 57 mm).

LENTON MASON LOCK taper-threaded splices:

4. After the cap has broken away, hand tighten the LENTON MASON LOCK coupler assembly onto the protruding male dowel.

5. To complete the installation, grip the exposed length of rebar protruding from the top of the block wall with a pipe wrench. Tighten the LENTON MASON LOCK assembly in a clockwise rotation until tight. Refer to supplied installation instructions for recommended tightness.
