20 Inch Over Travel Drawer Slides For Confident Closure

20 inch over travel drawer slides from Knape and Vogt in the 8419 Series are side mount ball bearing slides designed for projects that need smooth travel and controlled closing. The 1 inch overtravel lets the drawer extend past the cabinet front, giving better access to the back of the drawer during daily use or service work. A self closing feature helps pull the drawer shut at the end of travel, which supports consistent alignment of drawer faces without constant adjustment. The side clearance of 1/2 inch plus 1/32 inch minus 0 inch on each side defines the cabinet opening you cut, helping you plan box size and avoid field trimming. The slide height of 1-13/16 inch fits common drawer side layouts, so you can use it in many cabinet designs without reworking clearances.

Key Drawer Slide Details For Cabinet Projects

• The 1 inch overtravel lets the drawer move past the cabinet front, which improves reach to items at the back and helps when loading or cleaning deeper drawers.
• The self closing action engages at the end of stroke, which helps keep drawers consistently closed and fronts aligned in everyday use.
• The ball bearing design supports smooth travel, which feels better in use and helps prevent jarring loads that can affect alignment over time.
• The 1-13/16 inch slide height pairs with many drawer side heights, simplifying planning across a run of cabinets with similar construction.
• The 1/2 inch plus 1/32 inch minus 0 inch side clearance per side defines a predictable opening, which helps repeat installations across multiple cabinets.
• The anochromek finish covers the steel, which helps the slides present a consistent look inside the cabinet where hardware is visible.

Side Mount Slide Dimensions And Mounting Focus

This 8419B 20 model is a side mount drawer slide, so it aligns along the drawer sides and cabinet sides in typical face frame or frameless layouts that use this style. The specified 1/2 inch plus 1/32 inch minus 0 inch side clearance per side directly informs your cabinet inside width and drawer outside width, supporting repeatable fits in production or shop-built runs. The slide height of 1-13/16 inch defines the vertical space the hardware occupies, which matters when working near pullouts or stacked drawers. A 32 mm pattern is present, which ties into drilling systems that use that standard, aiding layout when boring rows or using line-boring equipment. The recommended fasteners are #7 x 1/2 inch Phillips pan head, which fits the slide holes and supports consistent anchoring into drawer members and cabinet sides.

Where These 8419 Series Slides Are Applied

The Knape and Vogt 20 inch over travel self close ball bearing drawer slides fit projects where side mount hardware is preferred and where access to the full drawer length is important. Their 1 inch overtravel lets drawers extend beyond the cabinet front, which is useful in deeper storage drawers or utility pullouts where rear access matters. The self closing feature suits cabinets that benefit from drawers being pulled shut at the end of travel, such as kitchen, shop, or office storage where fronts should rest in a consistent plane. Because the slide uses a 32 mm pattern, it aligns well with cabinet constructions that follow that hole system, supporting efficient drilling across multiple carcasses. The anochromek finish keeps the visual appearance uniform, which is helpful when slides are visible in open cabinetry or work areas.

Details That Support Repeatable Installation Results

The lever disconnect on this 8419 Series slide allows the drawer member to release from the cabinet member, which simplifies installing and removing drawers during fitting, finishing, or service. A ball retainer latch helps keep the bearing components positioned, which supports smooth operation during repeated cycles. Polymer stop cushions are part of the design, moderating the contact at the end of travel, which can help reduce noise at closing and lessen impact forces on the cabinet and drawer. The non-handed construction means the same slide works on either side, which streamlines inventory and reduces sorting time on site or in the shop. Sold in bulk pack as 10 pairs per box without screws, this format suits higher volume work where fasteners are already standardized and managed separately. The 8419B 20 part number clearly identifies this 20 inch length model, helping you match specifications across drawings, purchase lists, and installed hardware.
