Lid support 35-40 ft lb describes this Carlson Capitol Mfg. Company spring loaded lift mechanism designed to handle lids in the 35 lb to 40 lb range, which helps manage heavier chest-style or cabinet lids during everyday use. The product is part of the Lid Supports and Up Stays (Chest Style) family, so it is intended specifically to control vertical lid movement rather than general door motion. This unit is the left hand version, identified as manufacturer part 702LH-BLUE, which lets installers match handed hardware across a run of cabinets or chests. The support mounts inside the cabinet opening, so the mechanism stays within the casework footprint and does not project beyond the box. A solid brass enclosure slide is built into the design, helping the moving components travel smoothly along a guided path. Cover brackets are riveted to the cam, creating a fixed connection between the cam action and the lid interface for repeatable motion. High quality springs are available in different tensions for different lid sizes, tying spring selection directly to lid weight and height.
This lid support is designed for mounting inside of a cabinet opening, so the hardware locates on the interior structure rather than on exterior faces. That interior mounting keeps the mechanism aligned with the box construction as the lid moves. The 702 RH/LH Series is designed to be mounted to left or right side of cabinet, which gives layout flexibility for different case designs; this part number is the left-hand orientation within that series. The torque rating is expressed as lid height times lid weight times 1/2 per each support, linking the required support selection directly to physical lid dimensions and mass. Because the rating is per each, not pair, installers can calculate how many supports of this torque class are appropriate for a given lid. High quality springs available in different tensions for different lid sizes allow matching the spring characteristics to torque requirements, which supports more controlled motion when the lid is raised or lowered.
This Carlson Capitol Mfg. Company lid support belongs to the Lid Supports and Stays product class and the Work Surface & Tables|Lift Systems, Lid Supports and Stays|Lid Supports category, aligning it with casework and furniture lids rather than doors or drawers. It is described as a Lid Supports and Up Stays (Chest Style) Spring Loaded Lift Mechanism, indicating a role on upward-opening lids such as chests or similar cabinet tops. The support keeps heavy lids from slamming shut by using its spring loaded design and torque range to counteract part of the lid weight through its swing. That controlled closing behavior is important when users are working around stored contents beneath the lid. The support also holds the lid top open in any position, so users can park the lid at a comfortable angle instead of relying only on a fully open stop. Because this 702LH-BLUE model is a left hand unit intended for mounting inside of the cabinet opening, it suits installations where the hardware must stay within the interior while working against the side wall.
The exclusive cam action in this support holds the lid in any position, so once the lid is moved to a certain angle, the cam geometry maintains that angle without drifting. In a workshop or residential cabinet, that ability to hold without extra props keeps hands free for loading or unloading contents. The defined torque rating of 35-40 ft lb ties directly to the lid height and weight via the relationship torque rating equals lid height times lid weight times 1/2, guiding selection toward supports that work within this mechanical range. Because the rating is per each rather than per pair, designers can plan for one or more supports as needed to stay within the specified torque window for the application. High quality springs available in different tensions for different lid sizes enable closer matching between actual lid torque and the support's working range, which contributes to smoother motion through the lift and close cycle. The solid brass enclosure slide keeps the moving elements traveling on a guided brass track, which can help maintain alignment between the cam, springs, and brackets. Cover brackets riveted to the cam mean the cam's motion transfers directly and consistently to the lid connection point during every cycle. The statuary bronze/black oxide color finish allows the hardware to sit visually in darker cabinet interiors without drawing attention away from the casework. Together, these details aim to provide predictable opening resistance and position holding on chest-style lids where repetitive access is part of the workflow.
This lid support is described as a 35 lb to 40 lb spring loaded lift mechanism, so it is intended for lids whose weight and height produce torque within the 35-40 ft lb range.
The lid support uses an exclusive cam action that holds the lid in any position, allowing the lid to stay where it is placed instead of dropping or rising unexpectedly.
This 702LH-BLUE unit is designed for mounting inside of the cabinet opening, so it installs on interior cabinet structure rather than on exterior faces.
This product is the left hand version within the 702 RH/LH Series, which is designed to be mounted to the left or right side of a cabinet, depending on orientation.
The support uses high quality springs available in different tensions for different lid sizes, which helps match lifting assistance to the lid's torque requirements.
The 35-40 ft lb rating follows the relationship torque equals lid height times lid weight times 1/2 per each support, linking selection directly to the lid's size and mass.
The Carlson Capitol Mfg. Company 702LH-BLUE lid support brings a 35-40 ft lb torque rating, an exclusive cam action that holds the lid in any position, and a spring loaded lift mechanism tuned for lid sizes in this range. With mounting designed inside of the cabinet opening and a left hand orientation in the 702 RH/LH Series, it aligns with side-mounted chest-style lid layouts. The solid brass enclosure slide, riveted cover brackets, and statuary bronze/black oxide color work together to support both mechanical function and appearance. For projects where heavy lids must stay open steadily and close without slamming, this lid support offers a defined torque window and controlled cam-driven movement for repeatable performance.
