Purpose of these brackets on newer Isata 3 FW?
Snapped a pic of these heavy duty steel brackets on the underside of the full wall slide on an Isata 3 FW at the Tampa RV show last weekend. There are more than one and are mounted between the slide rollers. There are corresponding brackets mounted on bottom outer edge of the slide so that when the slide is closed the two halves "mate".
Would like to know the reason these have been added as the earlier models like mine do not have them.
