Trump transom torque

The form and function of U-MAX™ and MAX™ get a boost from a seemingly insignificant little screw. An external screw.

Frame fixing external to the glazing rebate provides structural support of the frame and glass without interfering with drainage. Not very flash, and yet, very awesome.

Our decision for this unique screw placement means less stress on the joint, improved structural performance and ensured water tightness. The glazing pocket is set at the perfect distance to get the best strength, minimize tilt, support the load and drain water. No other Front Glazed system supports transoms as well as this.

The increased strength and decreased risk of transom torque prevents the joint from opening up and allowing water in.

Break from tradition

Traditionally, systems either didn’t have a front screw at all or the screw came through the glazing pocket.

  • Often meant the split mullion needed to be wider than horizontals, losing visual unity.
  • A countersink operation was required to allow the mullion to mate.
  • The screw was placed central in the pocket and didn’t deal as well torsionally under wind load or take the dead weight of glass.
  • Without blocking off the glazing pocket, this scenario invited water to land on the screw and track underneath the pocket on top of the glass, making weathering suspect.

By breaking from tradition, we addressed all the above issues and delivered huge benefits with a little screw.
