HS12 Hold-Down Straps

To fasten ducts to the slab in shallow concrete. Used in place of duct supports. Straps maintain 1'' (25mm) spacing between ducts on multiple duct runs and prevent duct from floating during concrete pour. Attaches to slab with stakes or drive pins (not included). Locate Hold-Down Straps on approximate 5' (1.5m) centers. Duct Systems with both #2 and #4 ducts will require a 1/4'' thick shim to bring the top of the #2 duct level with the #4 duct. Consult factory for additional information.
