B-Line Eaton series conduit support fasteners, Conduit and cable, 1" Height, 1" Length, 1" Width, 0.077lbs, Conduit size: 0.75" EMT, 0.5" IMC, Rigid,

The Eaton B-Line BP-12-D4 conduit spacer bracket is sized for 3/4 inch EMT and 1/2 inch IMC or rigid conduit. Those trade sizes share the same outside diameter, which is why one bracket covers both. If you are running 1/2 inch EMT or 3/4 inch rigid, this is the wrong size and you need the matching bracket for that OD.

Yes. The BP-12-D4 spacer bracket is UL/CUL listed, so it satisfies inspectors on both US and Canadian jobs where listed support hardware is required for the conduit run.

A spacer bracket like the BP-12-D4 holds the conduit off the mounting surface rather than clamping it tight against it. That standoff is what you want on masonry, exterior walls, or damp locations where the raceway should not sit flush, and it gives room for the pipe to move and drain. A plain one-hole or two-hole strap pins the conduit directly to the surface with no clearance.

The bracket measures 1 inch in height, 1 inch in length/depth, and 1 inch in width, and weighs .077 lb. That compact footprint matters when you are spacing multiple parallel runs or working tight to a corner or a box.

The BP-12-D4 is the spacer bracket itself. Fasteners are chosen to suit the substrate, so order your own concrete anchors, toggles, or sheet metal screws to match the wall you are mounting to.

Yes, for runs using 3/4 inch EMT or 1/2 inch IMC and rigid it is a single part number to stock, BP-12-D4, with UL/CUL listing behind it. Any run in a different trade size needs its own bracket size, so plan your MRO stock by conduit OD rather than by bracket family alone.
