The new Hilti HIT-HY 70 Adhesive Anchoring System works in all masonry base materials: grout-filled block, hollow brick and CMU; and multi-wythe brick walls. The improved formula and innovative composite sleeve design provide strong, reliable and easy-to-install fastenings. Additionally, it cures in 45 minutes at 70°F, providing quick installation times.
Another advantage of the HIT-HY 70 system is when used in hollow masonry, the cap on the composite sleeve acts as a centering ring allowing better placement of the rod, as well as a providing a uniform dispersion of the adhesive resulting in a better keying effect. The cap is easily removable allowing composite sleeves to be snapped together to combine for custom lengths so various embedment depths can also be achieved. — Hilti, Inc., www.us.hilti.com
