HOHMANN & BARNARD, INC.
The Torq-Lok ® mechanical anchoring system is an easy-to-use and cost-effective method to re-connect existing veneers to various substrates. Anchors are manufactured of AISI Type 300 series austenitic stainless steel and ASTM Type 360 brass for a corrosion-resistant tie assembly. The 500 and 510 Series system consists of brass expansion elements that are situated in the veneer and backup segments of the wall system being rehabilitated. They are torque-activated, which provides a method of inspection for both the façade and backup connection. Use around bulging areas or sections that are to be removed. Can be used in high stress areas or to replace broken or cracked headers in composite walls. TORQ-LOK ® MECHANICAL RESTORATION SYSTEM
