T-Posts - an explaination
Take a look at the photos below. The first photo is of a typical window style with 4 sections, and opening windows at each end. You can see from photo 3 (the one with the open panels), that access is made easy by using the T-Posts to create a 'break' allowing each panel in the shutter to be hinged independently.
In addition to easy opening, T-Posts reduce the wear and tear on hinges and the frames, since a single panel carries half the weight of two bi-folded panels.
Many customers ask if there's a noticeable difference in how the shutter looks when it has T-Posts. A T-Post only adds another 25mm to the visible frame at the point of each T-Post, so actually, it doesn't really look so different.
