## Description

desertcart.com: Grab Bar Mounting Kit for Fiberglass Showers. The Solid Mount uses Adj. Spacers for use in most fiberglass showers with wood studs (Only). Solid, Secure, and won’t flex in your shower. Made in the USA : Health & Household

Review: Product works as advertised, is easy to install and is perfect for fiberglass tub/shower surrounds. - Great product and easy to install. My 1978 house has two fiberglass bathroom surrounds, one is a shower stall and the other a bathtub. I was worried about how to attach a safety grab bar on the fiberglass but with this product and the superb video and printed instructions, installation was a breeze. the most difficult part was finding the wall studs behind the fiberglass. After that, it was full speed ahead, drilling the holes and mounting the bar. There was no drywall between the fiberglass shower surround so the SolidMount was about the only option. Buy this product, it works great. Just follow the directions
Review: This provides a strong permanent attachment point - 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.

## 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.

## 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
