## Features

- ✔[Before You Buy]: Complete the pre-measure checklist and carefully review the full instructions in the Product Description below. Then, watch the available full installation video to ensure that The Solid Mount is compatible with your fiberglass shower and wood stud locations, that you have the necessary tools, and that you are prepared for the precise installation process. Doing so can also eliminate the need for a return, saving you time.
- [Compatibility}: The Solid Mount is designed for wood studs and most fiberglass showers. For contoured wall showers, install the grab bar vertically and apply extra caulking around the fiberglass and Solid Mount for a water-tight seal. It fits most grab bars (sold separately) with 2 1/2" or 3" round flanges from brands like desertcart Basics, American Standard, Moen, and Kohler. A visible 1/4" white ring will appear with the 2 1/2" flange. Not compatible with tile, marble, drywall, or any type of metal studs.
- [Design Concept]: The Solid Mount attaches to wood studs using adjustable spacers and a 5/16" x 4" (approx.) lag bolt through a 2" hole. Once installed, your grab bar (not included) is securely mounted for a water-tight fit. This system offers strong support independent of the fiberglass shower, reducing stress on the enclosure to prevent cracks and ensure safety and stability. Installation takes approximately 1 hour. Not compatible with tile, marble, drywall, or any type of metal studs.
- [Durable Materials]: The Solid Mount features stainless steel A2 screws, stainless steel washers, 5/16" x 4" (approx.) zinc lag bolts, and high-density proprietary plastic for lasting safety and stability. Developed through years of design and testing, our engineered Structural Plastic and hardware are thoroughly tested (contact us for documentation ). We confidently guarantee the product's quality and performance, with commercial lab testing supporting a 300+ lb capacity. (Not for shower chairs)

## Questions & Answers

**Q: Will this system work where fiberglass is backed by drywall?  Illustration shows no backing between fiberglass and studs.**
A: if there is drywall between the fiberglass and the stud drill the 2" hole to remove the drywall also. You must attach it to the stud.

**Q: The female adapter in the back side of the plate appears to be one inch or less, then why the two inch hole into the fiberglass panel??**
A: Re-read the directions and determine where you mis-understood the 2” hole. The depth of the distance between the wall stud and the tub surround is approximately 2” and the adapter is about 2”. The diameter of the hole starts at about 3/8” to 1/2” to look through and verify where the center of the stud is. The hole only has to be slightly larger than the adapter. Cut adapter so back side of round mounting plate presses against tub or shower wall. Be sure to use silicone adhesive to back of plate and to any attachment screws so you don’t have water leaking into the wall. When in doubt, hire a handyman.

**Q: Will this work with the moen 8912?**
A: As long as the flange is 3" dia

**Q: What size pilot hole drill to you need for lag screwd**
A: 3/16" pilot hole for the 5/16" lag bolt

## Customer Reviews

### ⭐⭐⭐⭐⭐ This provides a strong permanent attachment point
*by J***2 on September 8, 2025*

I purchased 3 of these kits (for 3 grab bars) and am glad I did. Takes about an hour to install one kit for each grab bar however it is well worth it. Instructions are easy to follow (video is also available), everything works as advertised. Provides a good, strong base anchored to stud behind shower/tub unit. This is a great way to add grab bars inside a shower/tub unit.

### ⭐⭐⭐⭐⭐ Mother in-law approved!
*by D***Y on April 3, 2025*

Made in the USA. This is an awesome product and the video is right on track. Watch the video before you order and again before you install. There were 2 different depths vertically which made for 2 different cut lengths as described in the video. In the end, the installation of the grab bar was rock solid and I have no concerns of the durability.

### ⭐⭐⭐⭐ Precise cut a,b,c,d marks
*by T***N on May 27, 2025*

This Bracket is solid you do not have to worry. It will come out. It has 6-Star directions/instruction are fantastic. The only thing is to make sure there are no leaks in shower where you cut the A,B,C,D marks the cut has to be super straight like put a level on it or the plate will not sit flush on shower wall. Other than that great product.
