Drywall Shims StraitFlex Leveling 1-1/2 x 45 x 1/16 Inch 100 Pack

Description

Product Overview

StraitFlex drywall shims are engineered to simplify the often tedious process of correcting framing irregularities. Each shim is a pre‑cut strip measuring 1‑1/2″ x 45″ x 1/16″ and is manufactured from high‑density compressed cardboard. This material choice provides a balance of rigidity and flexibility, allowing the shim to hold its shape under the weight of joint compound while remaining easy to trim if a slight adjustment is needed. The cardboard does not absorb moisture, so it will not swell or degrade when exposed to the typical damp environment of a construction site.

The design of these shims focuses on consistency. Every piece is cut to the exact same dimensions, ensuring that installers can rely on uniform thickness across an entire job. This uniformity reduces the time spent measuring and double‑checking each shim, allowing tradespeople to move more quickly from one task to the next. The packaging includes 100 strips per box, providing enough material for large residential projects or multiple commercial jobs without the need for frequent reordering.

Beyond the basic dimensions, the shims feature a smooth, flat surface that works well with drywall mud, joint compound, and other finishing materials. The surface does not fray or splinter, which means that when the shims are sanded after the mud dries, the result is a clean, even plane ready for paint or wallpaper. This quality contributes directly to a professional‑grade finish that meets the expectations of contractors and homeowners alike.

StraitFlex has also considered the logistics of jobsite storage. The shims are packaged in a compact, sturdy box that can be stacked with other building supplies. The box design includes a clear label that lists the dimensions and quantity, making it simple for inventory management and for quickly locating the right product during a busy workday.

Overall, the product combines material science, precision manufacturing, and practical packaging to deliver a reliable solution for leveling, shimming, and correcting minor framing errors. Whether you are a seasoned contractor, a DIY enthusiast, or a maintenance professional, these shims provide a cost‑effective way to achieve a level surface without the need for more invasive structural modifications.

Usage

These shims excel in a variety of scenarios where a slight adjustment is required to achieve a true plane. Common applications include leveling uneven studs before hanging drywall, creating a small inset at butt joints to prevent ridge formation, and filling gaps behind door jambs where the framing may be slightly out of square. Because the shims are thin yet sturdy, they can be inserted into tight spaces without obstructing other components such as electrical boxes or plumbing.

In residential remodels, contractors often encounter situations where cabinets or countertops have been installed on a floor that is not perfectly level. By placing a shim behind the drywall at the base of the cabinet, the installer can raise the surface just enough to align with adjacent walls, eliminating the need to rebuild the entire framing. Similarly, in bathroom renovations, shims can be used behind shower stalls to ensure the surrounding walls are perfectly vertical, which helps prevent water leakage and improves the overall aesthetic.

For commercial projects, the shims are useful when installing suspended ceilings or when creating a seamless transition between different wall sections. The compressed cardboard material does not interfere with fire‑rating requirements, and it can be coated with fire‑resistant joint compound if needed. The shims also perform well in high‑humidity environments such as kitchens and laundry rooms, as the material resists moisture absorption that could otherwise cause warping.

Why Choose Us

StraitFlex stands behind the quality of its shims with a commitment to durability and consistency. Each batch of shims undergoes rigorous testing to verify thickness tolerance, compressive strength, and resistance to moisture. This quality assurance process ensures that every shim you receive meets the same high standards, reducing the risk of unexpected failures on the job site.

Unlike wooden shims, which can split or rot over time, our compressed cardboard shims maintain their integrity even after repeated handling and exposure to joint compound. The material is also environmentally friendly, being sourced from recycled paper fibers and manufactured with low‑energy processes. This makes the product a responsible choice for contractors who are mindful of sustainability goals.

Customer support is an integral part of the StraitFlex experience. Our technical team is available to answer installation questions, provide guidance on best practices, and assist with any warranty concerns. We also offer a straightforward return policy for defective units, ensuring that you can keep your projects on schedule without unnecessary delays.

FAQ

Can these shims be used with wet joint compound?

Yes, the compressed cardboard material is designed to withstand the moisture in standard joint compound without swelling or losing strength. For best results, allow the compound to cure fully before sanding.

Are the shims fire rated?

The shims themselves are non‑combustible, but they should be covered with fire‑rated joint compound when used in assemblies that require a specific fire rating. This combination meets most building code requirements.

What is the maximum gap these shims can fill?

Each shim is 1/16″ thick, but multiple shims can be stacked to fill larger gaps up to approximately 1/4″. Stacking should be done carefully to maintain a flat surface.

Do the shims shrink over time?

No, the compressed cardboard is dimensionally stable. It does not shrink or expand with changes in temperature or humidity, ensuring the level you set remains accurate.

Can I paint directly over the shims?

After the joint compound has been applied and sanded smooth, the shims become part of the wall surface and can be painted or finished just like any other drywall area.
