Builders and repair people use these miracle workers that can be designed in various sizes, thicknesses, and styles to align parts, level surfaces, fill gaps, and perform other critical duties in a variety of construction and repair operations. Grove Shims is here to help you level objects easily and efficiently with our high-quality color-coded plastic shims. If one shim is not thick enough for the required adjustment, tap another shim in right next to the first one, but face it the opposite way. Shims that are not fastened may eventually drop out of the materials, leaving the materials unsupported. Once the door or window is plumb and level, drive a nail or screw from the casing, directly through the shims and into the framing to secure it.

Their high composite strength makes them ideal for aligning production and packaging equipment and other automation. Use a hammer or mallet to gently tap the shim into place, and use a level to check that the window or door is moving toward plumb or level as desired.So, if you are shimming up cabinets or subflooring near sinks, leveling a toilet, or other moist areas, plastic shims will be a better choice. Plastic shims are more expensive than wood, and cannot be welded like metal, which can make them the wrong fit depending on the application’s requirements. Plain and simple, a shim is a tapered wedge used for making slight adjustments to home elements, such as door frames and windows, to make them plumb (perfectly vertical) and level. It’s kiln-dried and slow-grown for strength and durability, whilst also being available in both Whitewood and Redwood.

If it’s loose and moves during the final installation, it could make whatever you’re trying to plumb uneven or misaligned.

Once a door or window is seated into the opening, place shims in any gaps between the window or door casing and the framed opening. Wickes Treated Regularised Kiln Dried C16 Timber has been graded to C16 strength for structural use and planed to regular widths for accuracy.
