If you've ever installed a window or door, you already know: shimming is everything. It determines alignment, structural stability, and long-term performance. But traditional shimming methods are time-consuming, inconsistent, and prone to costly mistakes. In construction, small mistakes don't stay small. That's exactly the problem Glazelock® was built to solve.
Who Is Tony Glazelock?
Glazelock was founded by Tony Glazelock, a professional window installer who experienced these inefficiencies daily. Instead of adapting to broken processes, he created a better one. That's a pattern seen across the trades: the best innovations come from the jobsite — not the office.
What Are Glazelock Shims?
Glazelock shims are a patented interlocking horseshoe shim system designed for precision spacing, faster installation, and consistent results.
- Interlocking stackable design — shim pairs stay together during installation
- Snap-off sizing for custom thickness without cutting
- Exact thickness control — precision-manufactured, not variable like wood
- High-impact, durable material — moisture-proof and non-compressible
- Made in the USA
Unlike traditional wood or plastic shims, Glazelock eliminates guesswork.
Why Contractors Are Switching to Glazelock
- Faster Installations: No cutting or stacking means less time per install
- More Accurate Results: Precise spacing reduces alignment issues and callbacks
- Reduced Waste: Reusable and consistent materials minimize jobsite waste
- Fewer Callbacks: Better installs mean fewer long-term problems
Why This Matters for Modern Construction
Today's contractors face rising labor costs, tight deadlines, and higher customer expectations. Products like Glazelock improve efficiency, consistency, and profitability. This is part of a larger industry shift: from improvised methods to engineered solutions.
