L.H. Dottie Pipe Supports & Offset Strut Straps

L.H. Dottie’s pipe supports and offset strut straps offer contractors a smart, durable, and labor-saving way to handle rooftop pipe installations and strut fastening. Built from UV-resistant ABS/AES material and engineered for strength, each support is lightweight enough to carry easily yet strong enough to handle heavy loads in demanding environments. The dual-channel pipe support design accepts both strut straps and 3/8-inch hardware, while the patented offset strut straps provide faster access, secure fastening, and reduced installation time.
