SL4 is 6.5" wide, 24" long and 3.5" tall with a non-welded set of 6 riffles held firmly down with a pair of clamps. Dog ears help create more flow while expanded metal captures the larger pieces of Gold in the first two riffles along with carpet liner running the length of all riffles. SL4 body is constructed with all aluminum, no welds and a handle for a lighter weight product to make packing in and out to your prospect a little easier.
