Drawer Slide Spacers Adjustable 5/8" - 1" - 100 Each

Drawer Slide Spacers Adjustable For Precise Fit

Drawer slide spacers adjustable 5/8 - 1 give installers a simple way to set roll outs and soft close slides to a consistent spacing, so cabinets line up cleanly and drawers travel smoothly. This Fastcap Miller Fastblock spacer uses a sliding block design that adjusts between 5/8 inch flat and 1 inch extended, which lets you bridge common gaps between the cabinet side and the slide without cutting custom shims. The spacer works with roll outs and soft close slides, so one part can serve across multiple cabinet projects that use these slide types. A load rating of 100 lb. means the spacer supports typical drawer slide loads in residential and light commercial cabinetry when used within that rating. The part is sold as a 100 each bulk box, which gives shops and installers enough units for multi-cabinet runs and repeat jobs.

Key Spacer Details That Support Slide Work

• The sliding block design adjusts from 5/8 inch flat to 1 inch extended, which lets you dial in the offset between cabinet side and slide instead of stacking scrap shims, saving layout and adjustment time on each cabinet.
• Compatibility with roll outs and soft close slides means the same spacer setup can be used across different drawer styles, helping keep hardware choices consistent from cabinet to cabinet on a project.
• The front of the spacer accepts a euro screw, or it can be flipped to work with slide screws, so you can fasten through whichever hole pattern your slide or cabinet system already uses without changing fasteners.
• Up and down adjustment of 3/16 inch lets you fine tune slide height at the cabinet side, which helps align drawer fronts and keeps pairs of slides running level for smooth action.
• The 100 lb. load rating gives the spacer capacity for many standard drawer slide applications, so typical kitchen, bath, or shop drawers can be supported within that limit during regular use.

Adjustable Spacer Setup For Drawer Slide Alignment

This Fastcap Miller Fastblock spacer adjusts in and out from 5/8 inch flat to 1 inch extended, so you can match the slide position to the cabinet side without milling fillers or ripping strips. The sliding block style lets you set the depth, lock the slide position, and repeat the same offset on additional cabinets, which helps keep multiple drawers aligned. Up and down adjustment of 3/16 inch on the spacer lets you nudge the slide vertically at the mounting point, so small layout differences in cabinet construction can be corrected without remaking parts. Because the spacer works with roll outs and soft close slides, the same installation approach can carry across different drawer box designs in the same job.

Where This Fastcap Spacer Fits Best In Use

Using The Spacer With Roll Outs And Soft Close Slides

The web description states this spacer is for roll outs and soft close slides, so it fits cabinet projects that use those slide types for pull-out storage. In roll out applications, the adjustable 5/8 inch to 1 inch range lets you stand the slide off the cabinet side to clear face frames or internal obstructions, keeping the box centered in the opening. In soft close slide setups, the same adjustable range helps set the slide in the correct operating zone so the soft close mechanism engages consistently. Because the spacer accepts a euro screw in front or can be flipped to use with slide screws, it ties into common cabinet construction methods using either system while holding the slide at the chosen offset.

Adjustment Features That Support Repeatable Results

Up and down adjustment of 3/16 inch gives enough travel to correct minor layout errors between cabinet members, which keeps slide pairs level and improves drawer tracking over the full extension. The in and out adjustment from 5/8 inch flat to 1 inch extended lets you standardize the reveal between drawer boxes and cabinet sides, so multiple openings can be set to the same depth without re-measuring each one. The 100 lb. load rating provides a numeric guide for how much weight the spacer is designed to support under typical drawer slide loads, which helps match it to everyday cabinet drawers used for storage. Sold in a 100 each bulk quantity, the Miller FASTBLCK BULK configuration suits production shops and installers who need a repeatable spacer across many cabinets.
