The number is the exact hole-to-hole distance in inches between the two mounting screws. That distance must match your wall's solid backing.
| Model | Hole-to-Hole | Works On | Best For |
|---|---|---|---|
| 12S | 12" | Any spacing, requires wood blocking | Tight spaces, tiled walls |
| 16S | 16" | 16" OC studs | Most U.S. homes |
| 24S | 24" | 24" OC studs | Older / custom homes |
| 32S | 32" | 16" OC studs (spans 2 bays) | Wider reach / coverage |
The screws will miss the studs entirely. A grab bar screwed only into drywall cannot support body weight. It will pull out of the wall and create a serious fall risk.
No. The 32S is designed for 16" OC walls only. It spans exactly two 16" bays (16" + 16" = 32"). On a 24" OC wall the holes will not align with any studs.
Wood blocking is a solid piece of lumber, typically a 2x6 or 2x4 board, screwed horizontally between two studs behind your wall surface. It gives the mounting screws something solid to grab when the bar's hole spacing doesn't line up with any single pair of studs.
The 12S has a 12" hole spacing, which is narrower than any standard stud spacing. Both screws will always land between studs unless blocking is added first.
Always fasten into solid wood studs or properly installed blocking. This is a safety requirement, not a recommendation.
The 16S, 24S, and 32S are rated to hold up to 600 lbs when properly installed into solid wood studs. The 12S achieves the same rating when installed into correctly secured wood blocking.
Yes. Extend-A-Hand grab bars are ADA-compliant and built to dimensional and load requirements specified in the ADA Standards for Accessible Design. They are manufactured by Mountain Manufacturing LLC under ISO 13485:2016 certification, the medical device quality management standard.
Tile over wood studs: Use a 1/4" carbide or diamond bit through the tile only, then switch to a 3/16" wood bit into the stud. Apply silicone sealant in each hole and around each screw before driving, to seal the wall cavity from water.
Masonry, concrete, or brick: Use rated masonry anchors sized for the bar and expected load. Drill pilot holes with a carbide masonry bit. Do not use standard drywall anchors in masonry under any circumstance.
Base tools (all installs): stud finder, level, pencil, tape measure, drill, 3/16" drill bit, #3 Phillips screwdriver (manual), safety glasses.
If installing a 12S with blocking: add 2x4 lumber cut to length, lag bolts or structural screws, and a saw.
If installing on tile: add a 1/4" carbide or diamond bit, silicone sealant, masking tape, water for cooling the bit.
If installing on masonry: add a carbide masonry bit, rated masonry anchors, and a hammer.
We offer a 30-day guarantee. If you've ordered the wrong size, reach out to us first. We'll help you confirm the correct model and arrange an exchange where possible.
The 3-year warranty covers manufacturing defects in materials and workmanship. It does not cover damage resulting from improper installation, specifically installation into drywall without solid backing or incorrect stud alignment.
Because these bars are manufactured in-house under ISO 13485:2016 standards, material and machining defects are rare. If you ever have a concern, contact us directly and we'll make it right.
Yes, please do. This is exactly what we're here for. Send us your stud spacing measurement and the location of the install (shower, toilet, hallway, etc.) and we'll tell you the correct model.
