Frequently Asked Questions
What is the 32 mm system for shelf pins?
European cabinetmaking spaces adjustable shelf-pin holes 32 mm apart on center in vertical rows. A jig with 32 mm hole spacing lets shelves move in 32 mm increments anywhere along the row.
Where do the front and back rows go?
Holes are typically set 37 mm from the front and back edges of the cabinet side, with each row's holes aligned 32 mm apart vertically. This keeps shelves level and supported near both edges.
How many holes will a panel need?
Divide the usable vertical run by 32 mm and add 1. A 640 mm tall section has 640 ÷ 32 = 20 spaces, so 21 holes per row, in two rows = 42 holes.
What pin and bit size should I use?
Most shelf pins use 5 mm holes (sometimes 1/4 in), drilled about 8–10 mm deep. Use a depth stop so you don't blow through the panel, and the 32 mm jig keeps spacing consistent across both rows.
