Half Lap Mullion Construction

Most mullion doors are manufactured by coping the mullion stock and gluing or stapling the pieces together.  However, Half Lap Mullion Construction provides stronger joints and a cleaner overall appearance. WalzCraft uses the Half Lap Construction with all stile and rail profiles (with exception to Mullion Molding Stock #2043).

Anchoring at the Strongest Point

Each horizontal and vertical mullion begins and ends at the strongest point: the inside edge of the cabinet door frame.

Mullions that run end-to-end also create more consistent grain flow throughout the lite pattern

Half Lap Mullion Joint - Back ViewKeeping it Clean

No pins or staples are used to join individual mullions together.  Only the half lap and a little glue are needed to create this clean and structurally sound mullion joint.

A Crafted Appearance

The precision of the half lap assembly produces virtually seamless mullion joints.

A half lap at each mullion intersection adds strength to the overall lite pattern by tying in more connection points to the inside of the cabinet door frame.

Frame & Mullion Retainer

Rubber Glass Retainer

All WalzCraft Frame and Mullion doors also feature an integrated retainer slot in the Stile and Rail Profile. Using the integrated slot and one of our retainer options is the easiest and most professional way to secure glass inserts into the cabinet door frame.  WalzCraft offers rubber retainer in Clear, White, Brown and Black.
