Center the bracket on the vertical stile on the outside face - that placement usually looks best. Run a strip of painter's tape across the top of the door first so you have a clean surface to mark on and to protect the finish.Most kits only give you one number: the gap from the top of the door to the underside of the roller, usually two inches. Cut a two-inch strip of cardboard, slip it under the roller as a spacer, and mark the center of each bolt hole through the bracket. Find the center of the stile too, so your holes sit dead center left to right."},{"number":2,"title":"Step 2: Drill the Bolt Holes and Bolt On the Hangers","text":"Chuck a spade bit in the drill and start each hole with the bit dead vertical. Push through only until you feel the tip poke out the back, then stop. Pull the bit out and finish the hole from the opposite side. Drilling straight through in one pass blows the grain out and leaves a ragged mess on the back of the door.Drill the first hole, bolt the hanger on loosely, and use the bracket itself as a template to mark the second hole. That keeps both bolts lined up so the hanger drops on clean. Snug the nuts with two crescent wrenches, working gently so you don't round over the black finish on the bolt heads."},{"number":3,"title":"Step 3: Rout a Guide Slot in the Bottom of the Door","text":"The floor guide rides in a groove in the bottom edge of the door, so you need to cut that slot before the door goes up. Tape the face of the door where the router base will slide so it can't scratch the wood. A router with a quarter-inch bit and an edge guide keeps the slot straight and centered.Run the router down the length of the bottom rail in a couple of passes rather than one deep cut. Go slow and let the bit clear the chips. If you don't own a router, a table saw or a track saw can cut the same slot, but the router with a guide gives you the cleanest result."},{"number":4,"title":"Step 4: Snap a Level Line and Mark the Track Holes","text":"Tape all the way across the header above the opening. Tan tape shows pencil lines better than blue. Find the horizontal center of the opening and mark it, then measure from the other direction to confirm it really is the center.This is the part people rush and regret. The bearings in these rollers are loose and free-spinning, so if the track sits even slightly out of level the door will roll open or closed on its own. Hold a good level on your line and check it. To lay out the mounting holes, tap a nail at the center point, hang the track on the nail, and mark each hole through the track itself. That guarantees the holes match the rail."},{"number":5,"title":"Step 5: Bolt the Track to the Header","text":"Your kit comes with lag bolts and spacer sleeves to mount the rail. Wrap a wrap of tape around the socket or driver first. If the spinning socket touches the rail it peels the finish and leaves an ugly ring around every bolt.Drive a pilot hole at each mark, then run the lag bolts home. Keep the driver square to the bolt and don't lean the socket against the rail while it spins. Snug each bolt firmly so the track can carry the weight of the door without pulling loose. If you can hit wall studs or solid blocking behind the drywall, do it - the whole door hangs off these bolts."},{"number":6,"title":"Step 6: Add the Stops and Hang the Door","text":"Before the door goes up, slide a track stop onto each end of the rail. These keep the door from rolling right off the end of the track and crashing to the floor. Get them on and snug - you can fine-tune their position later.Now lift the door and set the roller hangers onto the track so the wheels sit on the rail. This is the satisfying part where it finally becomes a door. Give it a gentle push and watch it glide. Center it in the opening so you have an even reveal of casing on both sides."},{"number":7,"title":"Step 7: Set the Floor Guide","text":"With the door hanging and centered, set the stop on the rail so the door lands in the right spot when it's closed. Then deal with the floor guide, which is the fussy part. It has to catch the bottom edge of the door both when the door is open and when it's closed, so its position matters.On carpet or an uneven floor, a wall-mount floor guide works well. This two-piece guide screws to the base of the wall or jamb and the adjustable fin slides into the slot you routed in the door. Slide the fin into the groove, sight down the door edge to keep the gap even top to bottom, and tighten the screws to lock it."},{"number":8,"title":"Step 8: Install the Anti-Jump Blocks","text":"One more step, and skipping it is dangerous. Right now the door can still be lifted straight off the track - a child could slam it and bring the whole slab down. Your kit includes small circular spacer blocks, sometimes called anti-jump blocks, that fix this.These blocks fit on the top edge of the door in the gap between the door and the underside of the track. They fill that space so the rollers can't hop off the rail. This is exactly why the two-inch top gap you set earlier matters - too little space and the blocks won't fit. Snap them in and the door is locked to the track. Add a handle and a flush pull whenever you're ready, and you're done."}],"recipe":null,"lastUpdated":"2026-07-15T16:49:48.702Z","published":"2026-07-15T16:49:44.941Z","license":"CC BY 4.0.
