Premium Black Plastic Shims For Accurate Door Alignment Jobs
✔️ Pack Of One Thousand Interlocking Shims For Quick Level And Secure Stacking

This pack of one thousand heavy duty interlocking shims helps you level and align openings quickly without messy adhesives. You will typically use them behind window frames, exterior door casings, cabinet mounts, and curtain wall setups where precise spacing matters. The collapsible locking design locks securely around bolts and anchors so stacks stay tight while you drill or fasten.

✅ Interlocking plastic construction locks together without tape or glue ✅ Resists rot, swelling, and shrinking in wet or outdoor jobsites ✅ Fits flush against anchor bolts for tight stacking during rough framing ✅ Made in the USA for consistent thickness and reliable load bearing

💡 Why choose interlocking plastic shims over traditional wooden wedges for rough framing alignment?
This block system is a handy fix for stabilizing openings while you work because the molded tabs lock directly onto hardware.
- They snap together to form adjustable wedges that slide easily into narrow gap spaces around door jambs
- The sealed plastic keeps its exact thickness when exposed to humidity so you never deal with warping parts
- You can build up thick support levels without taping small strips together which speeds up job site setup
