Ladder 3 Wire
3 Wire consists of 3 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.
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).
Standard: 9 gauge (.148 in) 9 gauge
Heavy Duty: 3/16″ (.187 in) 9 gauge
Extra Heavy Duty: 3/16″ (.187 in) 3/16″
