The Dayton Superior Bar Lock® Coupler System provides a simple, quick, cost effective method for splicing smooth or deformed rebar in tension and/or compression applications. Bar Lock® couplers are effective when used as a inch positional inch coupler when the rebar is fixed in place or when the rebar is free to rotate. Bar Lock® couplers utilize lock-shear bolts and serrated grip rails to mechanically splice the rebar. The serrated grip rails are embedded in the rebar as the lock-shear bolts are tightened. The heads of the lock-shear bolts are designed to shear off at a prescribed torque to ensure proper installation.
Fiberglass Composite Rebar is a high‐strength composite reinforcing bar engineered for concrete flatwork. 3MAX™ Composite Rebar replaces steel rebar and welded wire mesh in flatwork, providing centuries of serviceability to your reinforced concrete
To support one layer of steel above another and space them to required distance. May also be used to support steel on soft material form surface, such as carton forms or fill material.
