Dottie Pipe Supports are a revolutionary, lightweight, and cost effective solution for rooftop pipe supports. Their unique design makes it light enough to easily carry to the roof but strong enough to support extremely heavy loads. The Pipe Support is UV stabilized ABS/ASA material and maintains its effectiveness and characteristics within a temperature range from -40°C (-40°F) to 100°C (212°F). The support's dual-channel configuration accepts strut straps (in the large channel) and 3/8" bolts and 3/8" threaded rods (in the small channel). The 4' pipe supports (DPS) can be cut to any length to fit any job thereby reducing waste. The versatile 8” precut (DPS8) is a fast and easy solution for any job. With a load resistance of 130 lbs / in, dual-channel design, they are the smart choices for any job, in any climate.
