1000 Pcs 1/16 in x 3-1/2 in Stack Shims - Bulk Window & Door Shims

In this review of the 1000 Pcs 1/16 in x 3-1/2 in stack shims, the bottom line is simple: this pack is for tradespeople, contractors and serious DIYers who need a large, practical supply of thin, stackable plastic shims for door and window installation. The single biggest reason to buy is the combination of quantity and stackable design - 1000 shims in neat bundles makes repetitive leveling tasks faster and keeps small parts organized on the job. The review focuses on real-world utility rather than marketing claims.

Key Features

• Sufficient Quantity: A pack of 1000 shims eliminates frequent reorders and keeps a steady supply for multiple jobs or ongoing maintenance.
• Stackable Design: Each shim can be used alone or heat-sealed into 1-inch stacks for precise thickness control and quick adjustments at the frame.
• High Flexibility: At 3-1/2 in length and 1/16 in thickness, the shims adapt to varied gap sizes and allow fine tuning by stacking or trimming.
• Convenient Packaging: Bundles of 16 are organized for easy separation and storage, reducing time spent sorting small parts on-site.
• Sturdy Plastic Material: The engineered plastic delivers notable compressive strength so shims hold under pressure during installation and over time.
• Versatile Usage: Designed to fill gaps and evenly distribute pressure, the shims help protect frames and ensure accurate alignment of windows and doors.

Who It's For

This product is aimed at professional installers, carpenters and experienced DIYers who work on multiple doors and windows and value bulk supplies and consistent shim performance. The large quantity and organized bundles make it especially useful for jobs where speed and repeatability matter.

Those doing occasional single repairs or who require many thickness sizes beyond 1/16 in increments may prefer a smaller starter pack or assorted shim kit. This set is best when the 1/16 in baseline and stacking capability match the job's tolerances.

Pros & Cons

Pros

• Plenty of pieces per package, reducing downtime for reordering and restocking.
• Stackable and heat-sealable bundles simplify achieving exact thickness without fiddly trimming.
• Durable plastic resists compression and supports frames reliably during installation.
• Small, consistent size works well for fine adjustments and even pressure distribution.

Cons

• Only one thickness is supplied (1/16 in), so users needing many discrete thickness options must stack or trim to achieve larger gaps.
