It caps the open cut end of a run of strut so the sharp edges and the open channel are closed off. On exposed overhead racks and conduit supports that means no snag hazard for anyone working the ceiling, a finished look on visible runs, and dirt kept out of the channel. The B205ZN is a steel cap for B22 channel, 1.64 inches high by 1.62 by 1.62, and weighs about a tenth of a pound, so it adds nothing meaningful to the load on the hangers.

Electro-plated zinc on steel is an indoor, dry-location finish. It handles normal interior mechanical rooms, ceilings and plant areas fine, but for exterior, wash-down, or corrosive environments you want hot-dip galvanized or stainless caps to match galvanized or stainless strut. Pairing an electro-plated cap with outdoor galvanized strut is a common mismatch that shows rust bleed within a season.

B205ZN is the Eaton B-Line part number, the ZN suffix denoting the electro-plated zinc finish. Spec it by that number when you need the cap for B22 channel; the same cap body in another finish carries a different suffix.

No separate hardware is called out. The B205ZN is supplied as the steel cap itself, sized at 1.62 by 1.62 inches to the B22 channel opening, so it seats onto the cut end of the strut. Order one cap per exposed strut end, and count both ends of any free-standing run.

No. An end cap is a closure, not a structural fitting. At a tenth of a pound of electro-plated steel it protects the cut end and keeps debris out; it does not brace the channel, splice two lengths, or contribute to allowable load. For joining or reinforcing B22 strut you need splice plates, angle fittings or post bases, not this cap.
