CLC Cabinetry & Millwork Installation 2 — Questions and Answers
Question 1: When a cabinet must be installed against an out-of-plumb wall, what technique transfers the wall's irregular profile to the cabinet for a tight scribe fit?
- Back-cutting the cabinet side panel at 5 degrees
- Running a compass set to the widest gap along the wall surface (Correct answer)
- Applying flexible caulk to fill the gap after installation
- Shimming the cabinet away from the wall uniformly
Correct answer: Running a compass set to the widest gap along the wall surface
Setting a compass to the widest gap and running it along the wall transfers the exact wall profile onto the cabinet panel, which can then be trimmed to achieve a tight fit.
Question 2: What is the most common height for standard upper kitchen wall cabinets?
- 24 inches
- 30 inches (Correct answer)
- 36 inches
- 42 inches
Correct answer: 30 inches
30-inch upper cabinets are the most widely stocked standard height, fitting between the 18-inch countertop clearance and a typical 8-foot ceiling with space for crown molding.
Question 3: When laying out a corner base cabinet, what clearance condition must be verified before finalizing cabinet placement?
- The corner unit must rest on a continuous cleat
- Adjacent cabinet doors and drawer pulls must open freely without interference (Correct answer)
- The corner post must be plumb within 1/16 inch
- The lazy Susan shelf must sit exactly at counter height
Correct answer: Adjacent cabinet doors and drawer pulls must open freely without interference
Corner cabinet layout requires confirming that opening one adjacent door does not block the neighboring door or drawer from fully opening.
Question 4: What reveal (gap) size is typically maintained around inset cabinet doors and drawer fronts for a uniform finished appearance?
- 1/16 inch
- 1/8 inch (Correct answer)
- 3/16 inch
- 1/4 inch
Correct answer: 1/8 inch
A 1/8-inch reveal is the standard gap around inset doors and drawer fronts, providing adequate clearance for wood movement while maintaining a clean, intentional look.
Question 5: When securing upper cabinets to the wall, fasteners must penetrate wall studs by a minimum of how much to achieve adequate holding strength?
- 3/4 inch
- 1 inch
- 1.5 inches (Correct answer)
- 2.5 inches
Correct answer: 1.5 inches
Screws must embed at least 1.5 inches into the stud after passing through the cabinet back and wall material to provide the required shear strength for loaded cabinets.
Question 6: Which hinge type is fully concealed inside the cabinet when the door is closed, adjustable in three directions, and is the current industry standard for frameless cabinet construction?
- Piano hinge
- European cup hinge (Correct answer)
- Wrap-around hinge
- Surface-mount pivot hinge
Correct answer: European cup hinge
European cup hinges (concealed hinges) are mounted inside a bored cup hole in the door and clip onto a baseplate in the cabinet, allowing height, depth, and side adjustment after installation.
Question 7: When installing a long run of chair rail molding and a length joint is required mid-wall, what is the correct method?
- Butt joint the two pieces at any convenient location
- Make a 45-degree scarf joint centered over a wall stud (Correct answer)
- Cope both pieces and glue them together in the field
- Use a spline and glue joint at center span
Correct answer: Make a 45-degree scarf joint centered over a wall stud
A 45-degree scarf joint over a stud ensures both pieces are fastened to solid backing, and the overlapping cut minimizes any visible gap if the wood later shrinks.
