B-LINE DB5 – Frequently Asked Questions

1) How much weight can the B-Line Dura-Blok DB5 rooftop support hold?
The Dura-Blok DB5 block is rated for a 200 lb load. That is the rating for the single block, so on a run of conduit, pipe, or duct you space blocks so no one support carries more than 200 lbs of the total load including the pipe, its contents, and any strut or clamp hardware sitting on top.
2) How tall does the DB5 rooftop block raise pipe or conduit off the roof membrane?
The block itself stands 5 inches tall, so the bearing surface on top sits 5 inches above the roof. Anything you add on top, a strut channel or a pipe clamp, raises the pipe further. Footprint on the roof is 6 by 4.8 inches.
3) What is the B-Line Dura-Blok DB5 made of, and will it hold up outdoors on a roof?
Cast iron with an electro-plated finish. The plating is the corrosion protection on an exposed rooftop install. Cast iron gives it dead weight for a non-penetrating support, though at 2.75 lb the block relies on the load above it rather than its own mass for stability in wind.
4) What part number do I order for the 5 inch Dura-Blok, and how many do I need per run?
The model and manufacturer part number is DB5. Quantity is driven by your support spacing: divide the total supported weight of the run by the 200 lb per-block rating and space blocks so no single one exceeds it, then order the blocks plus whatever strut or clamp you are mounting on top, since that hardware is not part of the block.
5) Does the DB5 rooftop block come with strut, clamps, or mounting hardware?
The DB5 is the support block only. Channel, pipe clamps, and any fasteners are ordered separately to suit the pipe or conduit size you are carrying. Plan that into the takeoff before the crew is on the roof.
6) Will a 5 inch Dura-Blok give me enough clearance for pitched pipe and roof drainage?
Five inches of block height clears most flat-roof drainage and ponding zones for conduit and small line sets. If you need more elevation for a sloped drain line or a deeper insulation build-up, step up to a taller block in the Dura-Blok range rather than stacking, since the DB5 is a single 5 inch unit.
