Quick answer
Use a Kreg Rail Set to build cabinet doors with precise rail and stile joinery. The set simplifies alignment and clamping, so you can assemble strong, square doors consistently.
Why a Rail Set matters for cabinet doors
Cabinet doors rely on accurate rail and stile joints. A Kreg Rail Set holds the parts in perfect alignment while you drive pocket-hole screws, preventing the shifting that leads to gaps or out-of-square doors.
The set works with a Universal Bench, letting you build doors in a range of sizes. You can adjust the setup to match your project, from small cabinet doors to larger panels.
Choosing the right size
Kreg Rail Sets come in 14", 20", 28", 44", and 64" lengths. Pick the size that fits your largest door panel. For most cabinet doors, a 28" or 44" set covers typical widths. The 64" set suits wide doors or multiple doors in one setup.
If you build a mix of sizes, consider a longer set and adjust the stops. The set supports 30 possible bench sizes, from 14" x 14" to 64" x 64", so you can adapt as your projects change.
Steps for using a Kreg Rail Set
- Set up the rails: Attach the rail set to your Universal Bench, spacing the rails to match the width of your door stiles. Ensure the rails are parallel and level. Check that the rails are parallel before clamping; otherwise, your door will be skewed.
- Position the stiles: Place the stiles (the vertical door parts) between the rails. Use the stops to hold them firmly in place, ensuring the ends are flush. Tighten the stops evenly to avoid bowing the stiles.
- Install the rails: Set the horizontal rails (the top and bottom door parts) on top of the stiles. Align the ends with the stile edges, then clamp them securely. Double-check that the corners are square before clamping; a misaligned rail creates a twisted door.
- Drill pocket holes: Use a pocket-hole jig to drill holes in the rail ends. Position the jig according to your material thickness, and clamp it firmly to prevent shifting. Drill all holes before assembly to avoid moving the jig mid-project.
- Assemble the door: Apply glue to the joints, then drive pocket screws through the rail holes into the stiles. Use a clamp across the diagonal to keep the door square while the glue dries. Check for square by measuring diagonals; they should be equal.
Product facts
- Rail Set: Rail Sets are available in 14", 20", 28", 44", and 64" lengths and are made from heavy-duty 16-gauge steel. The steel construction keeps the rails rigid, so your door parts stay aligned during assembly, which is critical for square, strong joints.
