Your #1 Place for Plastic Shims

Plastic shims are spacer devices for helping building and fenestration contractors attain their goals of level, plumb and square.

Made from solid polypropylene, plastic shims are ideal for applications where leveling is required such as window and door shimming and cabinetry. The slotted center allows for easy fitting around existing screws, making leveling and alignment with plastic shims a quick and easy application.

Plastic horseshoe shims come in color coded standard thicknesses. They are also stocked in stacked and sheet styles. Not sure which style of plastic shims to use for your application? At Allfasteners, we have decades of experience with helping customers specify the correct tools and hardware for a great variety of jobs. We have backgrounds in building, engineering, safety and many other trades, so the advice you get from us is from first-hand experience.

Feel free to ask us any pre-purchase questions by calling 800 577 3171 or by emailing one of our sales representatives.
