Face-frame vs frameless: what changes for drawer slides?

Look at the structure around the drawer opening, not the style of its front. A face frame can put the opening in front of and inside the cabinet sides, changing where a runner needs support.

Match the opening you can see

Open the drawer enough to inspect the surrounding construction. Choose the closest description below; “Not sure” keeps that detail open. The choice records the cabinet context, not a slide type.

Why the front edge matters

Two top-view diagrams with the drawer omitted: a face-frame cabinet has a frame projecting inward at its front, while a frameless cabinet exposes the front edges of its side panels. — Top views, drawer omitted. The front opening and the space between side panels can differ in a face-frame cabinet. This shows construction only; it does not prescribe a bracket or spacer.

Face-frame cabinet: A separate frame surrounds the opening. Look behind it to see how the runner is supported. Depending on the system, mounting may use a specified rear bracket or another documented support arrangement.
Frameless cabinet: The cabinet side panels reach the front without a separate surrounding face frame. Check the side-panel fixing positions and material required by the runner’s installation instructions.
Dresser or other furniture case: Runners may attach to internal rails, blocks or other case members. Inspect those actual supports. Furniture construction is not automatically equivalent to a kitchen-cabinet mounting layout.
Not sure: Keep the context unconfirmed and check it when an attachment or fit decision needs it. You can still identify the running hardware or investigate a separate drawer problem.

Check the support before choosing a bracket

Follow the runner back. See whether it meets a side panel, block, rail or rear bracket. Check that the existing attachment is secure and undamaged.
Match the actual hardware. A rear bracket must belong to a compatible mounting arrangement; appearance alone is not proof.
Check the fixing material. Do not assume a thin back panel is the support required by the selected instructions. Look for the specified structural fixing surface.
Keep the runner path aligned. A usable front opening does not prove the mounting faces remain parallel or unobstructed farther inside.

A face frame does not mean every slide needs the same rear bracket. A frameless box does not remove the need to check fixings, setbacks or drawer geometry.

Apply the context to your job

For concealed runners, compare the box-sizing requirements before following the installation sequence.

If you are changing from side-mounted slides, use the conversion guide. Cabinet construction is one part of that decision, alongside box geometry, depth and attachment requirements.
