LW-340 & HW-340 Malleable Iron Wedge Inserts Wedge inserts are embedded into concrete slabs. Nail holes in the back of the insert allow easy nailing to forms. When the forms are stripped, the open face of the insert is flush with the concrete. The beveled head of the askew head bolt engages the internal wedge shape of the insert and produces an automatic tightening action when a load is placed on it. Available Hot Dip Galvanized. Note: LW-340 Long Wedge Insert is suitable for use at the bottom of the slab or when additional vertical adjustability is needed. HW-340 Standard Wedge Insert must be installed at least 1-1/2" from bottom of slab. 380-D Malleable Iron Adjustable Insert The 380-D is a malleable iron insert with an integral track that allows 3" of adjustability. A square nut is installed prior to nailing the insert to the formwork. When the forms are stripped, the face of the insert is flush with the face of the concrete. The sliding nut can then accept machine bolts or threaded rods for installation of precast panels, overhead piping or mechanical conduits. (Overall depth of insert is 2-1/2”.)

Chemically resecures veneer to concrete or masonry backup. Installation: Drill hole and blow clean. Mixing nozzle dispenses epoxy into screen tube. Insert tube into hole. When rod is inserted into tube, epoxy is displaced through screen, filling any voids in the masonry structure. When cured, epoxy forms an anchor connection that is capable of resisting positive and negative loads. Available in 1/4” - 3/4” diameters. Lengths as required. Rod and screen tube furnished in Type 304 Stainless Steel. #521RA-B Expansion type. Mechanically resecures veneer to concrete or masonry backup. Supplied with pre-installed O-ring to function as moisture drip. Installation: Drill hole through veneer into backup as required. With special 2-part tool, expand inner shield, then outer shield. Fill hole with mortar. Available 7”, 8” & 9” long. Type 304 Stainless Steel rod with brass expansion shields. Fits 1/2” diameter hole. #522RA Expansion/screw type. Mechanically resecures veneer to wood or metal stud backup. Supplied with pre-installed O-ring to function as moisture drip. Installation: Drill hole through veneer. With special tool, install threaded portion of anchor into wood stud, then expand outer shield into veneer. Fill hole with mortar. Available 7” long. Type 304 Stainless Steel. Fits 1/2” diameter hole in veneer. For material conformances, submittal sheets, CAD drawings and MSDS sheets see WWW.H-B.COM
