Face Frame Versus Frameless, What Changes On Site
Two systems, two different install problems
Homeowners choose between these on looks and storage. For whoever is doing the fitting, the difference is structural, and it changes the fastening method, the tolerance available, and how a mistake presents itself. A face frame box carries a hardwood frame, typically 3/4 inch thick and 1 1/2 to 2 inches wide, glued and doweled to the front edges of a plywood carcass. A frameless box, sometimes called European or 32 millimetre, is just the carcass: six panels, usually 5/8 or 3/4 inch, with the door mounted straight onto the side panel edge.
How they join to each other
Face frame boxes join frame to frame. Two adjacent stiles are clamped together with a face frame clamp, then drilled and screwed through the joint with a 2 1/2 inch screw. You are pulling 1 1/2 inches of solid maple against another 1 1/2 inches of solid maple, so the joint is stiff and it forgives a lot. If one carcass is twisted a hair, the frames still pull flush, and the twist disappears into the gap behind the frame where nobody will ever see it.
Frameless boxes join panel to panel, and the panel is what the door hangs on. Connector bolts or 1 1/4 inch confirmat style screws go through the side of one carcass into the side of the next, and there is no wide flat surface to clamp against, just a 3/4 inch edge. That means the two boxes must be shimmed to the same plane before they are drawn together, not after. Pull two frameless boxes tight while one is 1/16 of an inch proud, and the fastener locks that step in permanently, right on the face where every door reveal will be measured from.
Fillers and reveals
Face frame construction expects fillers. The frame overhangs the carcass anyway, so a 2 or 3 inch strip of matching stock scribed into a corner or against a wall is part of the design, not a patch. Reveals between doors on a face frame run are typically 1/8 to 1/4 inch depending on the overlay, and because the frame itself is the reference surface, minor carcass variation never reaches them.
Frameless runs are built on a grid. Reveals are commonly 3 millimetres between doors, sometimes 2, and every gap in the run is that same number. There is no frame absorbing anything. Because the doors cover essentially the entire face of the cabinetry, a filler in a frameless kitchen has to be a deliberate finished panel, cut and edge banded, and it will read as a panel. Slipping in an unbanded scrap to close a gap looks exactly like what it is.
Hinge adjustment, and what it can rescue
Frameless hardware wins here. A standard clip on 35 millimetre cup hinge gives three axes of adjustment at the mounting plate: roughly plus or minus 2 millimetres side to side, about 2 millimetres of depth on the cam, and 2 to 3 millimetres of height depending on whether the plate is slotted or cammed. That is enough to bring a door back parallel after a small install error.
Traditional face frame hinges vary. A concealed hinge on a face frame mounting plate offers a comparable range, but older style semi concealed and wraparound hinges often give lateral movement only. On those, the door position is decided when the frame is fastened to the wall, and the only remedy afterwards is to move the hinge.
Which one punishes a bad wall
Frameless, without question. Its tolerance budget is the reveal, so a wall that bows 1/4 inch across a 10 foot run pushes a box out of plane, the door follows the box, and a 3 millimetre gap becomes 5 millimetres at one end of a pair. That is visible from across the room. A face frame run on the identical wall hides the same error behind the frame, because the carcass can sit a little proud or shy while the frames stay coplanar.
This matters for the kind of housing common through the Yakima Valley, where lath and plaster walls and older stud framing are routine. Frameless work is entirely achievable there. It simply means the shimming has to be finished and checked before the boxes are drawn together, rather than adjusted out afterwards.
