Space Balls are small rubber spheres placed in the groove of a frame-and-panel assembly before the panel is inserted. They center the floating panel within the groove and allow it to expand and contract with changes in humidity without rattling or cracking the frame.

Coarse-thread pocket screws are designed for softwood, plywood, and particleboard — the coarse thread grips soft fibers more effectively. Fine-thread pocket screws are for hardwood, where the denser grain requires finer thread pitch for proper holding power without splitting. Always match the thread type to the material being fastened.

For 3/4-inch material, Kreg recommends a 1-1/2-inch pocket screw in most applications. Check the Kreg screw selector on the back of any Kreg jig box or consult the product listings for the specific screw diameter and head type that matches your jig and material.

Joinery biscuits are oval-shaped wafers of compressed beech wood that fit into matching slots cut by a biscuit joiner. When glue is applied, the biscuit swells slightly to fill the slot tightly, aligning and reinforcing the joint. They are commonly used in panel glue-ups, cabinet carcass assembly, and face frame attachment.

Door panel spacers are used during installation to position a door within its frame at a consistent, uniform gap on all sides. They make it much easier to achieve a level, properly gapped door hang when fitting entry or passage doors.

Yes. Use Kreg fine-thread pocket screws in the appropriate length for your material thickness when joining hardwood face frames. Fine-thread screws cut more cleanly in dense hardwood fibers and are less likely to split the wood at the joint.

Fastcap Izzy Skirt Washers are used to attach decorative skirts or trim panels to cabinet faces and furniture bases. The washer's design allows the panel to float and move with seasonal wood movement while staying securely attached — preventing cracking or buckling.
