    Description

    King Slide 9 Inch Soft Close Undermount Drawer Slides

    King Slide 9 inch soft close undermount drawer slides are full extension zinc undermount drawer slides designed for drawers built with 5/8 inch side thickness. These slides support concealed undermount installation, so the slide hardware stays out of sight while the drawer is in use. The full extension action lets the drawer travel completely out on the slides, which helps reach items at the back of a shallow 9 inch drawer. King Slide undermount's precision engineering provides a consistent glide opening motion, which matters on multi-drawer runs where users expect each drawer to feel the same. The design eliminates the telescopic bump present in most other undermount models, so the opening stroke feels smooth from start to finish. Extremely light pull opening force reduces the effort needed to start drawer movement, which supports easy operation for users of different strengths. The zinc material supports a durable slide body for typical cabinet environments.

    Soft Close Undermount Details That Support Workflow

    • King Slide undermount's precision engineering provides controlled glide opening, which supports repeatable, smooth drawer travel across a bank of drawers in kitchens, baths, or shop-built casework.
    • Extremely light pull opening force allows the drawer to start moving with less effort, which helps users open smaller 9 inch drawers without a noticeable initial resistance.
    • The hydraulic soft-close mechanism engages the drawer early in the closing motion, which extends the soft-close travel distance and helps the drawer close gently over a longer stroke.
    • The design eliminates the telescopic bump present in most other undermount models, which removes the mid-travel catch that many users notice when opening drawers.
    • The full extension slide action lets the drawer extend its full travel distance, which helps access contents positioned toward the back of the drawer space.
    • These slides are designed to be used with 5/8 inch drawer side thickness, which supports straightforward layout when drawer boxes are built around that material size.

    Undermount Slide Fit For 5/8 Inch Drawer Sides

    These King Slide undermount drawer slides are designed to be used with 5/8 inch drawer side thickness, which matters when planning drawer box construction and material choice. The undermount drawer slides mount beneath the drawer rather than on the sides, which keeps the cabinet interior visually cleaner and frees side clearance for the box. The full extension design lets the 9 inch drawer travel out to its working length, which supports access to items placed toward the rear of the box. Extremely light pull opening force means the force required to start drawer movement is low, which is useful when drawers are frequently accessed. The zinc finish provides a metal slide surface suitable for standard cabinet, furniture, or shop installations.

    Where These King Slide Undermount Slides Work Best

    Applications For 9 Inch Full Extension Undermount Slides

    These King Slide 9 inch soft close full extension undermount drawer slides fit projects needing short-depth drawers with concealed hardware, such as smaller cabinet bays or shallow storage sections. The undermount drawer slides configuration places the slides beneath the drawer box, which keeps the hardware hidden during normal use and leaves the drawer sides free of slide components. Full extension travel lets the front of a 9 inch drawer clear the cabinet face, which improves hand access to items stored toward the rear. Extremely light pull opening force supports frequent-use drawers where users benefit from an easy start to drawer movement. The zinc slide construction suits use in typical woodworking, cabinet, and furniture environments where metal slide bodies are standard.

    Soft Close Performance That Supports Repeatable Motion

    The hydraulic soft-close mechanism on these King Slide undermount drawer slides engages the drawer early in the closing motion, which provides an extended soft-close travel distance so the drawer slows and closes over a longer stroke. This early engagement helps reduce slamming as the drawer approaches the cabinet front. King Slide undermount's precision engineering provides a predictable glide opening feel, which is useful when multiple drawers in a run need to operate with similar feedback. The design eliminates the telescopic bump present in most other undermount models, which means the user does not encounter a mid-travel resistance change during opening. Extremely light pull opening force further supports smooth operation, since the drawer begins moving with relatively little effort. Together, these characteristics support a consistent, controlled drawer motion pattern from open through close.

    Common Questions About King Slide Undermount Drawer Slides

    What drawer side thickness do these King Slide 280-940 slides support?

    King Slide 9 inch soft close undermount drawer slides are designed to be used with 5/8 inch drawer side thickness, which helps align slide geometry with standard 5/8 inch drawer box construction.

    How does the hydraulic soft-close mechanism affect drawer closing?

    The hydraulic soft-close mechanism engages early in the closing motion, providing an extended soft-close travel distance so the drawer slows over more of its final stroke.

    What is the benefit of the full extension design on these slides?

    The full extension design allows the 9 inch drawer to travel its full length out of the cabinet, improving access to items stored toward the back of the drawer box.

    How does eliminating the telescopic bump change drawer operation?

    Eliminating the telescopic bump removes the mid-travel catch present in most other undermount models, so opening feels smoother from start to full extension.

    What role does extremely light pull opening force play in use?

    Extremely light pull opening force reduces the effort needed to start the drawer moving, which supports easier operation in frequently used storage locations.

    Why choose zinc King Slide undermount drawer slides for projects?

    These zinc King Slide undermount drawer slides provide a metal slide body with soft-close and full extension performance suitable for typical cabinet and furniture environments.
