B-LINE B121HDG – Frequently Asked Questions
1) What does the B-Line B121HDG strut fitting actually do in a strut assembly?
The B121HDG is an eight hole double corner connection fitting that joins strut channel at a 90 degree angle. Because it is a double corner design with eight bolt holes, it ties two runs of channel together across both legs of the corner rather than relying on a single-plane plate, which is what you want where the joint carries load in more than one direction, such as a trapeze hanger leg meeting a horizontal run.
2) Is the B121HDG corner fitting suitable for outdoor or wet locations?
It is hot-dipped galvanized steel, which is the finish specified for exterior, damp, and corrosive service such as rooftop mechanical supports, parking structures, tunnels, and wash-down areas. Plain or electro-plated fittings are the ones to keep indoors and dry.
3) Do bolts and channel nuts come with the B-Line B121HDG fitting?
No. The B121HDG is the fitting only. With eight holes you will need hardware for every hole you intend to use, so plan on strut nuts and bolts sized to your channel and sourced separately.
4) How thick is the steel on the B-Line B121HDG connection fitting?
Quarter inch. That 1/4 in material thickness puts it in the heavier class of strut fittings, above the thinner stamped plates used for light conduit and signage work, so it is the fitting for structural corner joints carrying pipe, duct, or trapeze loads.
5) What are the dimensions and weight of the B121HDG strut corner fitting?
It measures 3.93 x 5.37 x 3.5 inches (height, length, width) and weighs 1.52 lb. Check the 5.37 inch dimension against your clearance at the corner, since a double corner fitting projects along both legs of the joint and can run into adjacent pipe or an obstruction where a flat angle plate would not.
6) Should I use a double corner connection or a flat 90 degree angle bracket for a strut corner?
A flat angle plate bolts to one face of each channel and is fine for light, single-plane loads. The double corner connection wraps the joint on both sides, spreading the load over eight bolt holes and quarter inch steel, which is the choice where the corner is a structural node, sees vibration, or supports overhead pipe and equipment.
7) What is the correct part number to order this Eaton B-Line corner fitting by?
Order it as B-Line B121HDG. The HDG suffix is the hot-dipped galvanized version, so if the submittal calls for plain or pre-galvanized finish, that is a different suffix and a different part.
