* To have a nice uniform pressure on float flanges, you will use 2 sizes of flat washers: 3/8" &
1/2" on each lag screw.
** Since Leg holder has holes for 3/8" dia. bolts and that we are using the big 1/4" thick HD
corner, which has bigger holes, you will need to add 3/8" flat washers to combine those parts.
