Baitchef,, you won’t get 3 keepnet fittings onto 2 legs so you’ll need to invest in an accessories bar first of all. I use a Fox one which is excellent but most of the other manufacturers make them, just make sure they’ll fit the Boss legs ! You can then buy accessory blocks with threaded bankstick connectors or ones that take banksticks [short or long]. In fact you can add as many blocks as you want to take pole socks, tulips, feeder arms, etc, etc.
The best thing I can suggest is to get yourself a copy of the Preston catalogue and look at the Off-Box stuff to give you an idea of what’s available.

PS, Your Pro-Logic connectors will still fit on the accessory blocks as they’re all a standard thread.

have a look at the matchbox website

Make sure it will fit before parting with your hard-earned !

if you don’t fancy and accessory bar, i postition mine using acessory style arms rather than directly in front of the legs. I have it so one is in the middle, the the other two postitioned one either side. The matchbox ad adaptors work well for this as they rotate, and then you don’t have a huge metal bar to cart round.

baitchef the 6 drawer boss does it have internal legs with a footplate???or just internal legs ???

In fact, you can add as many blocks as you want to take polar socks, tulips, feeder arms, etc.
