Bobrick 251-4 – Frequently Asked Questions
1) Can I mount an ADA grab bar with the Bobrick B-251-4 WingIt kit without opening up the wall to add blocking?
That is exactly what the WingIt fastener is for. It installs through the finished wall surface into a hollow wall cavity, so there is no need to open and reconstruct the wall to add wood blocking or backing plate. Each fastener will support a 300 lb (136 kg) load.
2) How many WingIt B-251-4 fasteners do I need for one grab bar?
One fastener per flange. A standard straight grab bar has two flanges, so that is two fasteners; a three-flange or L-shaped bar takes three. Order by flange count, not by bar.
3) Will the WingIt grab bar fastener work in my wall? What cavity depth and drywall thickness does it need?
The B-251-4 is made for hollow walls with a cavity of 2-1/2 inch or 3-1/2 inch (65 and 90mm) or deeper, and finished wall surfaces from 1/4 inch to 1-1/2 inch (6 to 38mm) thick. The surface itself needs to be at least 0.625 inch (16mm) of painted or tiled drywall. A shallower cavity or a thinner wall board is outside what this fastener is rated for.
4) Can I use the Bobrick WingIt fastener on a solid concrete, block, or tile-over-mortar wall?
No. The B-251-4 is a hollow wall fastener, specified for wall cavities of 2-1/2 or 3-1/2 inches (65 and 90mm) or deeper behind a finished surface. Solid masonry, concrete, or a wall with no cavity behind the board needs a masonry anchor instead.
5) Does the B-251-4 WingIt fastener meet the 250 lb ADA grab bar load requirement?
The fastener is listed as ADA compliant and each one will support a 300 lb (136 kg) load, which is above the 250 lb point load figure written into the ADA accessibility standards for grab bars.
6) Will the WingIt fastener corrode in a wet shower or a high-humidity restroom?
The B-251-4 is stainless steel and specified as corrosion resistant, which is why it gets used behind tiled shower and bathroom walls in hotels, healthcare, and multi-family. The kit ships in a satin finish.
7) Is the B-251-4 a grab bar, or just the anchors?
Just the anchoring hardware. The B-251-4 is a WingIt fastener mounting kit for securing grab bar flanges to a hollow wall. The grab bar itself is ordered separately, and you need one fastener for each flange on that bar.
