Handles, gola and push-to-open

In short

1. 01A bar handle has two holes. The hole spacing is the size of the handle, most often a multiple of 32 mm, e.g. 96, 128 or 160 mm.
2. 02The handle screw must be longer than the front is thick. For an 18 mm front it is usually M4 × 25.
3. 03On base units the handle is near the top edge of the door, and on wall units near the bottom edge, so both are close to the worktop.
4. 04When the holes are in the same places on all doors, the handles line up across the whole kitchen.
5. 05A gola profile is a channel in the carcass for your fingers. The fronts have no handles, and the profile and the shorter fronts are decided in the design, before cutting.
6. 06With push to open, every front has a push latch. Fronts can also open by accident, and they usually go with hinges without soft close.
