B-LINE DB10 – Frequently Asked Questions

1) Do I need to penetrate the roof membrane to install a Dura-Blok support?
No. A Dura-Blok is a free-standing weighted base: it sets on the roof surface and carries the load by bearing, so no fastening through the membrane is required and there is no new penetration to flash or warrant. That is the whole reason contractors reach for a block support instead of a curb or a bolted stanchion. Set it on a stable, load-distributing surface and confirm the deck below takes the combined equipment and block weight.
2) How big is the Eaton B-Line DB10 Dura-Blok and how much does the block itself weigh?
The DB10 block measures 5 x 6 x 9.6 inches (height 5 in, length/depth 6 in, width 9.6 in) and weighs 5.28 lbs. That footprint matters twice: it sets the contact area spreading the load onto the roof membrane, and at just over 5 lbs a single installer can carry several up a ladder without a hoist.
3) Will a cast iron rooftop support hold up outdoors on a commercial roof?
The Dura-Blok DB10 is cast iron with an electro-plated finish, so the plating is what stands between the iron and the weather. Electro-plate is a thin sacrificial coating, not a hot-dip galvanize. It handles ordinary rooftop exposure, but treat any chip or drill mark as bare iron and touch it up. In coastal salt air or a corrosive process-exhaust plume, a plated cast iron block is the wrong choice and a galvanized or polymer-base support is the better call.
4) Is the Eaton B-Line DB10 the same thing as a channel nut or a strut fitting?
No, and the naming trips people up. The DB10 is a Dura-Blok rooftop support base, a 5.28 lb cast iron block that equipment or strut sits on. It is not a strut channel nut and does not thread onto anything. If what you need is the spring nut that slides into the channel to take a bolt, that is a separate part ordered by channel size and bolt thread.
