Lid support 55-65 ft lb from Carlson Capitol Mfg. Company is a spring loaded lift mechanism designed to control heavy lids in work surface and table applications, so a raised top stays where it is set instead of dropping unexpectedly during use.
This 703-BLACK lid support mounts inside the cabinet opening at the center, so it works in chest-style installations where a single central support is preferred for a balanced lift on wider lids.
An exclusive cam action in the mechanism holds the lid in any position, so the user can stop the lid at a comfortable working angle without it drifting or slamming while accessing the cabinet interior.
High quality springs in the mechanism are available in different tensions for different lid sizes, and the 55 to 65 foot pound rating matches heavier lids where controlled motion is important for day-to-day operation.
The torque rating is defined as lid height times lid weight times one half per each support, which gives installers a clear way to calculate whether this specific 55-65 ft lb model fits the actual lid dimensions and weight on a project.
The 703 Series is designed to be mounted to the center of the cabinet rather than the sides, which suits chest-style layouts where a single support must manage the lift and hold functions along the lid centerline.
A solid brass enclosure slide inside the mechanism guides the moving components as the lid travels, providing a defined path of motion that supports repeatable opening and closing cycles over the life of the cabinet.
This 703 Series center mount lid support is designed for mounting inside the cabinet opening, so the mechanism sits beneath the closed lid and works within the cabinet envelope rather than projecting outside the case.
The torque rating formula of lid height times lid weight times one half per each support gives a direct link between the hardware specification and the physical lid dimensions, so installers can size the support to the actual application.
Because the 703 Series is dedicated to center mounting, layout work focuses on aligning the support along the lid centerline, which simplifies placement compared with side-mount versions that must be mirrored.
The exclusive cam action and solid brass enclosure slide operate together during installation testing, so once the mounting points are set, the lid can be raised and lowered to confirm that the cam holds positions smoothly through the designed range of motion.
This Carlson Capitol lid support sits in the Work Surface & Tables, Lift Systems, Lid Supports and Stays category, so it fits projects where a horizontal surface lifts to reveal storage or mechanism space below.
Mounting inside the cabinet opening keeps the support within the case, which suits chest-style cabinets and bench storage where exposed exterior hardware is not desired and the motion is contained under the lid.
The spring loaded lift mechanism serves chest-style lids that fall into the 55 to 65 foot pound torque range, so heavier tops such as substantial cabinet lids or work surface panels benefit from controlled opening and closing.
The 703 Series is defined as a center mount design, so it is aimed at layouts where a single central support manages lid motion instead of paired side supports, which can simplify hardware selection for straightforward chest designs.
The web description notes that the 702 RH/LH Series is designed to be mounted to left or right side of a cabinet, while the 703 Series is designed to be mounted to the center of the cabinet, clarifying which series applies when a central location is desired.
The statuary bronze and black oxide color finish on this 703-BLACK model presents a dark hardware appearance at the mechanism, which can visually blend with many interior cabinet finishes in woodworking settings.
The exclusive cam action that holds the lid in any position works with the spring loaded lift to resist unintended movement, so when a user stops lifting, the lid stays put, supporting safer hands-free access to the cabinet interior.
Because the torque rating is defined using lid height, lid weight, and one half per each support, the same formula ties directly from design drawings to hardware selection, reducing guesswork when choosing the 55-65 ft lb model.
High quality springs available in different tensions for different lid sizes allow the torque range to be tuned within the product family, so the 55-65 ft lb specification aligns with lids that require stronger lifting and holding force.
The solid brass enclosure slide guides the internal moving parts, so repeated lifting cycles track along a controlled path, which helps maintain consistent cam engagement and position holding over many open-close operations.
Cover brackets riveted to the cam create a fixed structural connection within the mechanism, so the motion of the lid passes directly into the cam profile that provides the holding action, supporting repeatable lid stopping points during daily use.
The center mounting design of the 703 Series focuses all lift and hold activity along the center of the lid, so when the torque calculation is matched to the lid, the support can manage balance and control from a single location within the cabinet.
This lid support is specified at 55-65 foot pounds, matching heavier lids that fall within that torque range so the spring loaded mechanism can control lift and holding performance.
The torque rating uses lid height times lid weight times one half per each support, giving installers a direct formula for matching this 55-65 ft lb model to a specific lid.
This 703 Series model is designed to be mounted to the center of the cabinet, so it aligns along the lid centerline instead of the left or right sides.
The exclusive cam action holds the lid in any position, allowing the lid to stay at the angle where lifting stops, which supports steady access to the cabinet interior.
The solid brass enclosure slide guides the internal movement of the lid support, helping the lid travel smoothly and supporting consistent operation over repeated opening and closing cycles.
The 703-BLACK lid support has a statuary bronze and black oxide color finish, giving the mechanism a dark appearance that coordinates with many cabinet interior finishes.
The 703-BLACK center mount lid support from Carlson Capitol Mfg. Company brings a spring loaded lift mechanism, 55-65 ft lb torque rating, and exclusive cam action together to hold chest-style lids in any position during regular work.
With a solid brass enclosure slide, cover brackets riveted to the cam, and a statuary bronze and black oxide color finish, this support offers controlled motion and a dark hardware appearance inside work surface and table cabinets.
For projects that specify a single central support inside a cabinet opening, this 703 Series design aligns the mechanism along the lid centerline, tying cam action, torque rating, and spring strength directly to heavier lid applications.
