StringA-Level Tile Support System

April 7, 2010

StringA-Level™ System

For shower wall tile installations in any standard or custom configuration


Designed primarily for shower wall tile installations, the STRINGA LEVEL Tile Support System is for use on any wall mounted tile installation where tiling begins above the floor.

The system is a set of reusable tools that eliminate time wasting straightness and level problems with wood stringers.

The system is comprised of interlocking sections with level vials that are used in series to form a continuous angle support shelf on which the first course of tile rests.

The sections are temporarily attached to the wall with user supplied screws and washers through multiple slots in each section.

Available in kit and component form with illustrated usage instructions.

3. Hold first section to mark and secure one end of STRINGA-LEVEL to wall using backer board or drywall screws. The use of 1/4 inch washers is also recommended to prevent damage to screw slot edges. Extend piece making sure bubbles are in the level position and screw in opposite end.

NOTE: Be sure not to over tighten screws. Just snug against wall is all that is necessary to hold STRINGA-LEVEL in place.

Finish by screwing the inner slots as needed.

Frequently Asked Questions

Do I purchase pieces individually?

StringA-Level is available separate or in kits. The Standard Kit (SLSK-0204) includes 4 red rigid sections and 2 yellow flexible sections. It will cover a 3′ x 5′ or smaller shower. The Contractor Kit ( SLSK-1010) includes 10 of each. Both kits include a storage bag. The flexible and rigid sections and each of their corresponding bubble vials are also available individually.

Why should I use washers?

Durock, Hardi Board, high/low thread type screws have ribs under the head that helps embed them into the hard material. Over time, these ribs start to take a toll on the slots by shredding them. The use of washers prevents this from happening.

What do I do if StringA-Level doesn’t layout perfectly?

Individual sections do not need to interlock in order for StringA-Level to be useful. Their strength and accuracy won’t be compromised if sections cease, then begin again around outside corners. Inside corners can be bridged instead of the flexible pieces fitting in tight, etc.

We at Flooring Supply Shop thank you for your purchase of STRINGA-LEVEL™ and are confident you will be pleased with its performance.
