Lid support 40-45 ft lb describes a spring loaded lift mechanism designed to hold a heavy lid on a cabinet or chest style opening, so the lid stays controlled instead of dropping. This Carlson Capitol Mfg. Company 703-GREEN lid support mounts at the center of the cabinet opening and works as part of a work surface or table lift system. Its exclusive cam action holds the lid in any position, turning the support into a positioning device rather than just a counterbalance. A solid brass enclosure slide guides the motion smoothly along the travel path, which helps the lid move predictably as it opens and closes during repeated use. Cover brackets riveted to the cam create a permanent connection within the mechanism, which keeps the moving parts aligned once installed. High quality springs available in different tensions match different lid sizes, so the 40-45 ft lb rating can be chosen to suit lids that fall in that torque range.
The 703 Series is designed to be mounted to the center of the cabinet, so layout revolves around a single support aligned with the lid and opening. For installers, this central mounting style simplifies lining up the lift mechanism with the lid geometry on chest style cabinets. The inside-of-cabinet mounting keeps the spring loaded lift hardware within the cabinet opening, which keeps the mechanism operating in line with the lid during opening and closing. Because the exclusive cam action holds the lid in any position, the installed support can function as both a lift and hold-open device. The 40-45 ft lb torque rating directly connects to lid height and lid weight, using the formula noted for torque rating as lid height times lid weight times one-half. This rating gives a quantifiable way to match the 703-GREEN support to the lid being mounted.
This lid support is described for mounting inside of a cabinet opening, so it is suited to cabinet and chest style lids where the mechanism lives behind the front edge. In these applications it works within work surface and table lift system layouts under the Work Surface & Tables and Lift Systems, Lid Supports and Stays category. The 703 Series is designed to be mounted to the center of the cabinet, placing the lift mechanism on the centerline of the lid. That center mount configuration fits cabinet designs where a single lift point handles the lid loading rather than side-mounted pairs. Because high quality springs are available in different tensions for different lid sizes, the same style of mechanism can be used across a range of lid dimensions by choosing the torque rating that fits the lid torque formula. This flexibility supports multiple cabinet projects using a consistent hardware type.
The exclusive cam action that holds the lid in any position means the mechanism does more than simply push up; it provides stable holding at various angles. This behavior matters when a user wants the lid top open in any position during access to the cabinet, because the cam can resist unwanted closing. A solid brass enclosure slide guides internal motion, and brass as the slide material supports repeatable movement of the lift components within the enclosure over many open-close cycles. Cover brackets riveted to the cam fix those brackets permanently to the cam element, so the geometry between the cover connection and the cam profile remains consistent. The torque rating of 40-45 ft lb, defined by lid height times lid weight times one-half per each support, quantifies the working range, and this stated formula ties the selection of the spring loaded lid support directly to actual lid measurements. The statuary bronze/black oxide color finish supplies a dark-toned look that visually recedes inside many cabinet interiors while aligning with other dark hardware in the assembly.
The 703-GREEN unit is a spring loaded lift mechanism in the Lid Supports and Stays product class, used to support and control a heavy cabinet or chest style lid.
The 703 Series lid support is designed to be mounted to the center of the cabinet and is described for mounting inside of the cabinet opening for chest style lids.
The exclusive cam action in this lid support holds the lid in any position, so the lid top can stay open at intermediate angles during cabinet access.
The 40-45 ft lb torque rating follows the formula lid height times lid weight times one-half per support, linking the mechanism to a specific lid size and weight.
The 703-GREEN lid support uses a statuary bronze/black oxide color finish, giving the lift mechanism a dark appearance inside the cabinet or chest.
High quality springs are available in different tensions for different lid sizes, so a spring rate can be selected that aligns with the lid torque requirements.
The Carlson Capitol Mfg. Company 703-GREEN lid support, with its 40-45 ft lb torque rating, serves projects where a heavy lid needs controlled support from a single, center-mounted mechanism. The exclusive cam action that holds the lid in any position adds functional value for chest style cabinets, because it lets the lid top stay open while the user works at the opening. A solid brass enclosure slide and cover brackets riveted to the cam form the internal structure that guides this spring loaded lift mechanism through its travel. Within Wurth Baer Supply offerings in Lid Supports and Stays, this statuary bronze/black oxide color support fits applications matching the stated torque formula for lid height and weight, making it a focused choice when specifying hardware for a cabinet or work surface lid.
