Conduit strap for 3-1/2 in pipe

The DOTTIE HW409 two-hole strap secures rigid conduit or pipe with a 3-1/2 inch trade size. Steel construction with zinc plating resists corrosion in indoor and covered outdoor locations. Electricians and maintenance crews use it to meet support spacing requirements on long runs.

Two-hole mounting pattern

The strap provides two pre-drilled holes for lag bolts or screws, anchoring the conduit firmly to wood, masonry or steel framing. This pattern distributes load across both fasteners and prevents the pipe from rotating under thermal expansion or vibration.

Fits 3-1/2 in trade size conduit

The formed steel body wraps the outside diameter of 3-1/2 inch conduit without crushing the wall. Zinc plating protects the strap itself; the installer supplies appropriate fasteners and ensures the mounting surface can carry the weight of the filled raceway.

Questions about this item

How does the 3-1/2 inch size work once the strap is installed on a conduit run?

The two-hole strap clamps 3-1/2 inch conduit or pipe firmly against the mounting surface, holding it in line without crushing the wall.

What mounting standard does the HW409 follow and what thickness of surface can it handle?

It uses two standard bolt holes for lag screws or bolts; the zinc-plated steel ears accept typical 1/4 or 3/8 inch fasteners into wood, steel or masonry.

What clearance and hardware do I need to mount this strap?

Allow space for two fastener heads; the strap body is flat steel, so it sits flush against the surface once the bolts are tightened.
