Ladder Series 200 design is a prefabricated reinforcement for embedment in the horizontal mortar joints of masonry. It is manufactured in 10′ 8″ lengths from wire conforming to ASTM A1064/A1064M, ASTM A82/ A82M It consists of two or more parallel and deformed longitudinal wires welded to a perpendicular cross wire spaced 16" O.C. Out-to-out spacing is approximately two inches less than the nominal thickness of the wall. Standard: 9 gauge side and cross rods Heavy Duty: 9 gauge cross rods and 3/16" side rods Extra Heavy Duty: 3/16" side and cross rods For CMU walls: 4", 6", 8", 10" and 12"
16" O.C. ladder design positions cross rods on web of block to allow core clearance. Simplifies rebar installation; centering utilizes strength of grout. Allows unrestricted flow of grout or loose fill insulation into CMU cells. Minimizes re-setting of joint reinforcement around rebar. Improves resistance to shrinkage cracking. Provides stronger bond with cross rods in web of block. Less time devoted to rebar installation, grout pouring. Meets ASCE/ACI 530 building code requirements for masonry structures and ASTM A 951 (standard specification for masonry joint reinforcing).
