Total system weight capacity: 150 lbs. For biparting, both doors combined must stay under 150 lbs. Over 150 lbs? Face-mounted styles in this collection handle up to 220 lbs; see heavy duty hardware for over 200 lbs.
Door thickness: 1-3/8 in to 1-3/4 in. Outside this range? See heavy duty hardware.
Wall clearance beside opening: Must equal full door width on the slide side. Limited clearance? See bypass or bifold hardware.
Wall header: A solid header above the opening is required for track mounting. If there is no existing header or backing in the wall, we recommend installing a minimum 1×6 hardwood board (3/4 in thick × 5-1/2 in wide) that extends past the length of the track to the next stud or structural support point on each side. No solid header and cannot install one? See ceiling mount hardware.
Ceiling clearance above door: 5 in required.
Door width: Your door must be wider than the rough opening. For standard rooms plan for 2 in of wall overlap on each side — opening + 4 in. For bedrooms and bathrooms, 3 in per side gives better privacy — opening + 6 in. Minimum functional overlap is 1/2 in per side. See our measuring guide for full sizing formulas.
Door height: Measure from finished floor to the top of the rough opening and add 1 in. The extra inch covers the top of the opening while leaving 1/2 to 1 in of clearance at the bottom for the door to slide without dragging. If you have thick carpet, check that clearance is adequate along the full travel path before ordering.
