Outside L-Frame

What Is An L-Frame?

An L-frame, as its name suggests, is designed in the shape of the letter 'L'. There are two types of L-frames: one for inside mounting, and another for outside mounting your shutters. An outside mount L-frame will project further than an inside mount. In this article, we'll discuss the L frame used for Outside Mounting.

What Is An Outside Mount L-Frame?

An outside L-frame is mounted to the architrave or frame of your window, depending on the type of window. If you do not have the required clearance for an inside mount, an outside L-frame is a great alternative.

If you are outside mounting, your window will protrude slightly from the wall. Outside mount shutters have a projection into the room of 63.5mm
