How to Trim a Pocket Door Jamb How to Trim a Pocket Door Jamb
The final touch to installing a pocket door is to attach and trim the door jambs. Trimming the jambs for a pocket door is a much different process than for a regular door. This project requires jambs on both sides of the inside pocket; as well as on the door frame for a professionally finished appearance. Take your time and you will have a perfectly finished pocket door.
Step 1 - Measure the Pocket Side Jambs
Measure the height on both sides of the pocket side jamb. Cut a 1 by 4 inch board to this measurement. Use a circular saw for this cut. Now, measure the pocket door frame from the edge of the pocket to the edge of the wall. Generally 1 by 1/4-inches but it is best to measure for accuracy.
Step 2 - Cutting the Pocket Side Jambs
You are going to rip or cut lengthwise the pocket side jambs. You will need to use the rip blade with the circular saw for this cut. You will be cutting with the grain. The rip blade gives you a clean cut and helps avoid splitting the board.
Step 3 - Attaching the Pocket Side Jambs
Take the cut piece and line it up with the inside of the pocket door frame. Make sure it lines up flush. Secure it with screws. It is wise to drill pilot holes for the screws throughout this project, thus avoiding splitting the wood.
Step 4 - Measure the Header
At the top of the pocket door frame, measure the length on each side. Measure the width from the wall to the edge of the pocket door frame.
Step 5 – Cut the Header
Cut a 1 by 4 inch board then rip to the measurements with the circular saw and rip blade.
Step 6 - Attach the Header
Use wood screws and screw driver to attach the jambs to the header on both sides of the pocket door frame.
Step 7 – Measure the Solid Jambs
Measure the height of the solid side of the pocket door frame. Measure one side of the opening from the drywall edge to the opposite edge of the drywall on the other side of the opening.
Step 8 – Cut and Attach the Solid Jamb
Using the height measurement for the solid jamb cut the 1 x 4 inch board with the circular saw. Using the measurement of the opening; rip the cut board. Attach the solid jamb to the pocket door frame.
Your pocket door is now ready to install the casing. You may want to glue the trim or use very short screws for this finish. You don’t want to scratch those new pocket doors. If you are installing the pocket doors on unfinished floors, you may find it necessary to use a jamb saw to trim the bottom of the installed jambs prior to laying the flooring.
