Square Threaded Stem Glide Inserts are used to securely hold Adjustable Threaded Stem Glides. These inserts are installed and concealed inside of the hollow leg tubing of your school furniture and made to accept any 1/4" x 20 threaded stem glide.

Installation is easy, simply push the Glide Insert inside of the square furniture tubing. Once inside, the metal holding clips will keep the inserts securely in place.

Threaded Glides can be manually adjusted by tightening or loosening the threaded portion of the glide to level out the furniture. 

Available in three sizes to fit round-tubed school furniture from most common brands.

• Fix Wobbly or Uneven Furniture: Threaded Stem Glide Inserts used in combination with Threaded Stem Glides allow you to adjust each individual glide to the desired height.
• Secure Fit: Threaded Stem Insert holds the glide firmly to the furniture leg tubing. Add an optional nut to secure through the tubing or flat steel leg bottom.
• Durable and Dependable: Glide Inserts feature a rust-resistant plated steel construction, engineered to last.
• Compatibility: Available in multiple sizes to fit square tubed school furniture with an outside diameter of 7/8”, 1”, or 1-1/8”.

Be sure to confirm the correct size option when ordering Threaded Stem Square Tubing Glide Inserts for your school. You can do this by measuring the existing chair leg tubing with our free Measuring Wizard or simply with a ruler or tape measure.
