Many manufacturers hold their shutter panels together with just a few dowels at the corners and a bit of glue. This means that the actual surface contact area is minimal and the panel can easily break.
The rails (horizontal frame members) of O'Hair shutters are milled with a protruding piece (or "tenon") that fits into a corresponding slot (or "mortise") in the stiles (vertical frame members). Depending on the shutter design, the tenons range in width from just under two inches to over 11" for the largest rails. That is huge! In addition, they are assembled with tenon screws that draw the tenon tight for an unassailable bond.
With some competing panels, if you drop them on the corner, the entire panel can literally fall apart. O'Hair shutter panels are absolutely rock-solid and built for absolute reliability.
