SubPiggy Arms, Flat, pair

The SubPiggy is shipped standard with 2 sets of arms, but can fit anywhere from 4 to 6 depending on which rail width is ordered.  Expand a SubPiggy by adding these arms which are identical to the ones shipped standard.  Flat arms have support edges 6.75" deep.  By allowing gear to overhang the front and back, gear up to 13" deep can fit on a SubPiggy. Thick rubber trim prevents gear from sliding around on the arms. Note:  These arms are similar in size to those on the Gear Rail, but they are not identical.  As a result they are not interchangeable.
