Yes, you're missing an insert that acts as a gasket and supports the coax
cable. You're probably also missing the tube of "goop" that seals the unit
around its periphery.

Subject: [TowerTalk] B&W Center Insulator for dipoles
> One of my junk drawers just coughed up a B&W cast aluminum center
insulator for dipoles. It is a two piece clamshell design that is really
heavy duty with eye bolts, ceramic insulators, gaskets and seems to want to
clamp to the coax feedline.
> My question to the old timers out there is why is hole for the coax 9/16 "
diameter, much too large for RG-8 type coax? Am I missing a part that is a
gasket of some kind that would make the RG-8 fit?
>
> If this B&W unit is used correctly, I seems like it could take a LOT of
tension and weight of coax hanging a long way down. I plan to raise my 80 M
dipole to heights it has never seen before!
