Blum 1/2″ Overlay Mounting Plate

This zinc die-cast mounting plate with nickel-plated finish delivers the ±3.5mm height adjustment that makes face-frame cabinet doors align properly. Worth the investment for contractors who build or renovate face-frame cabinets — the most common cabinet construction in Montana homes. The edge-mount design works where wrap-around plates won’t fit on narrow stiles.

Skip it if you’re working with frameless European-style cabinets. This plate is specifically engineered for face-frame construction with 1/2 inch (13mm) overlay.

Technical Specifications and Installation

The elongated screw holes provide ±3.5mm of vertical adjustment — enough range to fix doors that sag or bind without remounting the entire hinge system. That matters when you’re hanging 20 doors in a kitchen and need them all to line up perfectly.

The plate is designed for use with Compact 33 hinges (130. and 133. series T-nut system). Installation follows a straightforward sequence: align the plate on the edge of the cabinet face-frame, mark and pre-drill pilot holes if necessary to avoid splitting the wood, secure the plate using wood screws through the elongated adjustment holes, then attach the Blum Compact 33 hinge by inserting the T-nut into the plate arm and tightening the mounting screw.

Build Quality and Longevity

The zinc die-cast construction handles the stress of daily door operation better than stamped steel alternatives. Montana’s humidity swings — from bone-dry winters with wood stoves running to humid summers — test cabinet hardware. The nickel-plated finish provides corrosion resistance that matters when cabinets see decades of use.

Blum plates are often praised for their precise manufacturing tolerances — critical when you’re aligning multiple doors across a run of cabinets. The weight of 0.060 lbs per unit indicates substantial construction without being heavy enough to stress cabinet frames.

The Limited Lifetime Warranty covers defects in materials and workmanship for the original homeowner/purchaser but does not cover damage from improper installation, misuse, or normal wear and tear.

Who Should Buy This

Cabinet installers working on face-frame projects need these plates. The edge mount design fits narrow face frames where wrap-around plates won’t work. Edge mount (130.1100.23) is easier to install on narrow face-frames, whereas wrap-around plates (130.2100.23) provide more stability but are often discontinued or harder to find.

The ±3.5mm height adjustment saves time during installation and allows for seasonal wood movement correction without remounting hardware. Meets or exceeds ANSI/BHMA A156.9 Grade 2 standards — real durability testing, not marketing fluff.

Frequently Asked Questions

What screws work best with this mounting plate?

Use #6 x 5/8” wood screws. Some retailers include screws, others sell them separately. Pre-drill pilot holes in hardwood to prevent splitting.

Will this work with all Blum hinges?

No. This plate is designed for use with Compact 33 hinges (130. and 133. series T-nut system). It’s compatible with Blum’s Clip Top and Blumotion hinges (not for INSERTA hinges).

How does this compare to integrated hinge designs?

The 130.1100.23 is a separate plate for the Compact 33 hinge, allowing for more flexibility and part replacement, whereas the Compact 38N/39C often features an integrated hinge/plate design. Separate plates let you replace worn components without changing the entire hinge system.

Is door adjustment possible after installation?

Yes. Adjust the door height by loosening the plate screws and sliding the plate up or down. The ±3.5mm range via elongated screw holes provides enough adjustment for most alignment issues.
