Salice F70 21 inch push to open undermount drawer slides use a full extension undermount design so the drawer travels completely out while keeping hardware concealed, which helps keep cabinet lines clean while still giving full access to stored items. The true progressive action described for these slides means both members move together in a single smooth motion, which supports controlled drawer travel along the entire stroke. A stated 170 lbs static load capacity allows the F70 slides to support heavier drawer contents at rest, which is useful for deep kitchen, shop, or office drawers that hold dense items. The 154 lbs dynamic load capacity rating describes the maximum load while the drawer is moving, so the slide can handle frequent opening and closing cycles under real use. An integrated push opening system lets the user open the drawer by pressing the front, removing the need for handles and supporting handle-free cabinet designs.
The F70 slides are identified as undermount drawer slides, meaning they mount beneath the drawer box instead of on the sides, which leaves drawer sides flush for clean interior and exterior lines. The web description calls these PROGRESSA PLUS FF push open slides, indicating a face frame oriented configuration that is suited to face frame cabinet construction where the frame defines the opening. Compatibility with 1/2 inch to 5/8 inch and 3/4 inch drawer side thickness gives flexibility in drawer construction, allowing use with common side material sizes in many shop standards. Full extension operation combined with the synchronized mechanism keeps the slide travel coordinated as it moves under the rated load, which supports consistent alignment when fitting multiple drawers in the same cabinet bank.
These Salice America F70 21 inch undermount drawer slides are categorized under drawer slides and slides, undermount, placing them in applications where concealed undermount action is preferred over side-mount hardware. The PROGRESSA PLUS FF push open designation describes a face frame configuration that suits cabinets built with a front frame, which is common in many residential and commercial shop projects. Their compatibility with 1/2 inch to 5/8 inch and 3/4 inch drawer side thickness supports building drawer boxes from standard panel stock, so the same slide model can serve multiple drawer sizes within a job. The full extension design allows drawers in kitchens, offices, or workshop cabinets to open completely, so items at the back of the drawer can be reached without shifting contents forward.
The true progressive action mechanism stated for these slides moves the drawer in one continuous motion, which supports predictable travel when aligning fronts across a run of cabinets. The integrated push opening system eliminates the need for external pulls, which can simplify layout work on slab fronts or matched-grain fronts that rely on a clean surface. The 170 lbs static load capacity and 154 lbs dynamic load capacity ratings keep performance tied to defined load numbers, which helps plan where to place heavier storage drawers within a cabinet bank. Meeting and exceeding ANSI BHMA A156.9-2020 Grade 1 standard, and being identified as WI approved, ties these slides to recognized performance standards, which is useful when projects require hardware documented to specific grades. The undermount configuration keeps the mechanism out of the way of drawer contents, which helps keep interior width free for organizers or larger items.
