Hanger Bolts AB
For the suspension of rectangular ductwork with threaded rods.
Instead of screws a Hanger Bolt is screwed at the lower airduct corner and used as suspension point.
Sturdy and economical solution for connecting ductwork to threaded rods.
Easy installation.
Installation Instructions
Instead of the standard bolts and nuts two AB Hanger Bolts are fitted in the holes of the duct´s bottom corner pieces. Care must be taken when tightening the bolts that the hole for the support threaded rod remains vertical. Only the bottom holes must be used, not only because it allows adjustment of the support rod, but also for safety reasons - the bottom corners cannot be pulled out from the duct easily.
Sound isolation
With SI Isolation Hangers or DB Ceiling Brackets.
If ducts have external insulation, the supporting rods can be approximately 5 cm longer and a Long Nut (please refer to section “GS Threaded Rods/LM Long Nuts“) or collar 30 mm long is installed instead of the normal nut. This enables the height of the duct to be adjusted even after it has been insulated.
