GE Streamline:
Unique one, maybe one of the only cast styles made. Has bumps on the faces to lock into each signal section.
Round Center Hole Style #1
One large center hole, then there are both three square carriage bolt holes as well as three round bolt clearance holes.
Round Center Hole Style #2
One large center hole, then there are just three square carriage bolt holes you use on both sides.
Round Center Hole Style #3
This is practically the same as style #2 but the center hole is much larger.
Triangle Center Hole Style #1
The center hole is three connected [round] holes making a larger Y-hole. Rather like a Mickey Mouse with a tiny head. There are three square carriage bolt holes.
Triangle Center Hole Style #2
The center hole is three connected oval holes making a larger Y-hole - the connection between the three holes has clipped, instead of curved flowing, edges. More of a radiation alert symbol. There are three square carriage bolt holes.
3M Ring Connector
I'm told this style is used on 3M signals. It's slightly larger than the normal rings, only has two carriage bolt holes, and has a large "double D" ring hole in the center.
Poly Signal Connector
What do you use to join a poly signal? Why a poly connector of course. It is a plastic fender washer shape, it has a central connector bolt hole surrounded by four pentagon shaped holes.
) And my Econolite 9" ped looks like it has 'round center #3'. (all depending on the exact diameters/bolt hole shapes that is...?)
Thanks!
