B-LINE 4A-18-SR12 – Frequently Asked Questions

1) What tray widths does the B-Line 4A-18-SR12 straight reducer connect?
The 4A-18-SR12 reducer transitions an 18 inch wide tray run down to a 12 inch wide run. It is a straight reducer, so both trays stay on the same centerline rather than offsetting to one side.
2) Which B-Line tray series does the 4A-18-SR12 fitting belong to?
It is a Series 2-5 fitting, so it is intended to land on B-Line imperial cable tray and ladder in that series range. Confirm your existing run is Series 2 through 5 aluminum before ordering, since fitting rail profiles differ between series.
3) I need to reduce an 18 inch tray to 12 inch but keep one side flush against a wall. Is this the right fitting?
No. This is a straight reducer, which centers the 12 inch tray on the 18 inch tray and pulls in evenly from both sides. To keep one rail in line for a wall or a cable drop off one edge, you want an offset or left/right hand reducer instead, not the SR12.
4) Is the B-Line 18 inch to 12 inch straight reducer aluminum or steel?
Aluminum. That keeps the piece light, 3.9 pounds, so a single electrician can set it in place overhead, and it matches aluminum Series 2 through 5 tray rather than a galvanized steel run.
