What our customers say.

  • We have been using Glazelock’s Interlocking shims for over 5 years now. They simply snap together to get our desired thickness. No more taping or glue shims together, saving us time and money.

    – Roger, Starline Architectural Windows Ltd.

  • We at Softer Lite Window Company use the Wedgelock Shim and are pleased with this great product.  My installers find it more efficient and cost-effective, and an easier and faster way to get the job done right-the first time.  We recommend the Wedgelock Shim and all of the Glazelock products.

    -Mark Kane, President, Softer Lite Window Company

  • Glazelock is our go to company for all our shim needs.  We’ve never had any problems with the product received.  The customer service provided goes beyond expectations-we can see our product ordered as soon as the next business day.

    -Lindsey Holmes, B&D Contractors, Inc.

  • I like using Glazeock’s Stackable Shims because they have the ability to stack well and make the right size shims for the job.
