DSR701 surface mount door straightener is a Sugatsune America post-production solution designed to fix warped doors so they close more cleanly in everyday use. This DSR701-1830/B-10 straightener is made to run the complete height of the door, which distributes correction along the full slab rather than only at hinge points, helping the door maintain a more consistent plane. The adjustable design corrects doors within a 56-5/16 inch to 72-1/16 inch length range, giving flexibility across common interior door sizes on a project. A black finish lets the straightener blend with dark door backs or hardware layouts where a low-contrast component is preferred. The product is classified as passage door hardware, so it fits directly into typical passage door builds where swing and clearances matter. Being installed after the door is hung supports corrective work without rebuilding the opening.
The DSR701 surface mount door straightener can be partially recessed or surface mounted to the back of the door, giving flexibility for jobs that call for a more concealed install or a simpler surface application. For partially recessed installation it requires M4 (U.S. #8) flathead wood countersunk screws, while surface mounting uses wood panhead screws, so fastening matches the mounting style. An adjustment range of plus or minus 10 mm can be made from the top of the door with an M4 Allen key, allowing fine tuning from the head of the door without disturbing the rest of the assembly. The straightener must run the complete height of the door, so layout and routing or surface placement follow the full stile length rather than segmented runs.
This Sugatsune 56-5/16 - 72-1/16 inch DSR701 surface mount door straightener is intended for passage door hardware applications, placing it directly on the back of interior doors where warp affects swing and latch performance. The minimum 16 mm (9/16 inch) door thickness requirement targets typical interior wood or composite door constructions within that build range. Because it can be partially recessed or surface mounted to the back of the door, it fits both new production doors where a shallow channel can be machined and retrofit cases where surface fixing is preferable. The need to run the complete height of the door means it is laid out from top edge to bottom edge along a stile, so the straightening force works with the structural length of the door rather than a short repair section.
The plus or minus 10 mm adjustment from the top of the door with an M4 Allen key allows controlled correction after the straightener is mounted, so the installer can dial out warp in small increments instead of bending the door by feel. Accessing adjustment from the top edge means the door can remain hung while that 10 mm range is used, supporting faster fine tuning during punch-out work. The ability to cut the straightener from the bottom by up to 400 mm lets the same DSR701-1830/B-10 part number adapt to shorter doors inside the 56-5/16 inch to 72-1/16 inch operating range, which simplifies part stocking while still matching individual door heights. Selecting surface mount with wood panhead screws or partially recessed mounting with M4 (U.S. #8) flathead wood countersunk screws ties the installation method directly to the desired visual profile and door edge detailing. Running the straightener the full height interacts with that adjustment range to spread corrective pressure evenly, which supports doors staying flatter once set.
The DSR701 surface mount door straightener adjusts for doors between 56-5/16 inch and 72-1/16 inch in length, so it serves a range of common interior passage door heights within that span.
The DSR701 door straightener can be partially recessed into the back of the door or surface mounted, letting installers choose between a more concealed channel or a simpler surface application.
The DSR701 straightener uses M4 (U.S. #8) flathead wood countersunk screws for partially recessed installs and wood panhead screws for surface mounting, matching fastener style to the mounting method.
The DSR701 straightener offers plus or minus 10 mm of adjustment from the top of the door using an M4 Allen key, allowing precise correction while the door remains in place.
The DSR701 door straightener can be cut from the bottom by up to 400 mm, so it can be trimmed to match specific door heights while keeping the top end for adjustment access.
The DSR701 surface mount door straightener is specified for a minimum door thickness of 16 mm, or 9/16 inch, aligning with many interior passage door constructions.
The Sugatsune DSR701-1830/B-10 surface mount door straightener provides post-production correction for warped doors within a 56-5/16 inch to 72-1/16 inch range, making it useful across multiple passage openings. Its requirement to run the full door height, combined with a plus or minus 10 mm adjustment from the top with an M4 Allen key, gives controlled straightening rather than trial-and-error bending. The option for partially recessed or surface mounting on the back of the door, along with a black finish and 16 mm minimum door thickness rating, ties the part directly into typical interior door hardware layouts.
