Double the keystones! (The most flexible port mount for wiring?) Contained the same rear corner skirt size. I tried 5 keystones horizontally (3+2) but it was gross looking.

Works on all Trident sizes (250, 300, 350) since only the rear centre panel length changes.

Same exact keystone hole dimensions as VoronDesign (attributed source).

I tried to make it as ‘OEM’ as possible, but a lot of hex had to go in order to support keystone lips and not look gross.
