DSR701 surface mount door straightener installs on an existing door to fix warped doors after installation, so doors that have twisted or bowed in service can be brought back into alignment without replacing the slab. The Sugatsune America DSR701-1830/S-10 door straightener is designed as passage door hardware, so it works as part of the overall door assembly rather than as cabinet hardware. Its silver finish identifies it clearly on the jobsite and blends with common contemporary hardware finishes for an unobtrusive look on the back of the door. The straightener runs from 56-5/16 inches to 72-1/16 inches, so one part number covers a wide range of standard interior door heights while keeping inventory simple. The product can be installed as a surface-mounted or partially recessed component on the back of the door, so installers can choose the method that best suits the door thickness and job requirements.
The DSR701 surface mount door straightener works on doors from 56-5/16 inches to 72-1/16 inches in length, so it covers many common interior door sizes with one adjustable profile that can be cut as required. The product requires a minimum door thickness of 16 mm, or 9/16 inch, so it suits many lightweight wood or composite doors that still need stiffness support. The straightener can be installed as a partially recessed profile or fully on the surface of the back of the door, so it adapts to existing door prep and visual requirements. Cutting from the bottom up to 400 mm tailors the part to shorter doors while keeping the top-end adjustment features intact for reliable field tuning.
This Sugatsune America DSR701-1830/S-10 door straightener is part of passage door hardware, so it is intended for use on swinging doors rather than sliding or cabinet fronts. It installs on the back of the door, so it operates out of sight from the pull side and works along the stile that needs correction. The minimum door thickness of 16 mm means it suits many lighter interior doors, so it can be used where cores are not heavy but still experience warp over time. Because it must run the complete height of the door within its 56-5/16 inch to 72-1/16 inch range, the straightener distributes correction effort over the full door height, helping the panel hold a flatter plane against the stop. Cutting from the bottom up to 400 mm allows the same product to fit shorter doors while keeping the working section near the top intact, which maintains the adjustment function at the top edge.
The plus or minus 10 mm adjustment from the top of the door, using an M4 Allen key, provides controlled movement along the straightener so the installer can gradually pull a bowed edge back into line with the frame. Adjusting from the top concentrates the working mechanism at an accessible edge, so small changes can be made while the door is hanging and the reveal is visible. The option to mount the DSR701 partially recessed or on the surface of the back of the door lets installers balance speed and appearance, since a recessed fit tucks the straightener into the edge while a surface mount keeps routing to a minimum. The requirement for M4 (U.S. #8) flathead wood countersunk screws for partially recessed installation, or wood panhead screws for surface installation, ties the hardware directly into typical wood doors, providing familiar fastener geometry during installation. The silver finish on the door straightener keeps the component visually consistent along its length, which can be important in service situations where components need to be matched by eye across multiple openings in a project.
The Sugatsune DSR701 surface mount door straightener works on doors between 56-5/16 inches and 72-1/16 inches, so one part number handles a range of standard interior door heights.
The DSR701 straightener mounts to the back of the door and can be partially recessed or fully surface mounted, so installers can match their preferred machining style and visual requirements.
The DSR701 straightener provides plus or minus 10 mm adjustment from the top of the door with an M4 Allen key, allowing controlled correction of warp while the door remains hung.
The DSR701 surface mount door straightener requires a minimum door thickness of 16 mm, or 9/16 inch, so it suits many lightweight interior wood or composite doors.
The DSR701 straightener can be cut from the bottom by up to 400 mm, allowing the same unit to fit shorter doors while keeping the top adjustment section functional.
The DSR701 uses M4 (U.S. #8) flathead wood countersunk screws for partially recessed installation, or wood panhead screws for surface installation, matching common door fastening practice.
The Sugatsune DSR701-1830/S-10 surface mount door straightener is designed to fix warped doors after they are already in place, so it suits punch-list and service work where door replacement is inefficient. Its 56-5/16 inch to 72-1/16 inch length range, plus or minus 10 mm adjustment from the top, and minimum 16 mm door thickness requirement define a clear working envelope for interior doors. Selecting this silver-finish straightener for qualifying openings lets you address bow and twist using a product built specifically for post-production correction across common passage door sizes.
