The Bulkhead Plates
U. L. System # W-L-3316

Bulkhead Plates are Special Order Items. They work as the inside washers for our Split Sleeve Systems to repair large holes and multiple cable penetrations. We take pride in the fact that we are able to offer a 24 hour turn around time on these systems! From cable tray penetrations to major holes, we can build you a set of these. When you use one of these Systems, you will only need one slotted square washer for Split Sleeves, for each side, to invert 180 degrees from the slot in the plate.

Plates can be configured with any combination of 1 - 2 - 4 inch holes and slots...... they can come from the top, bottom, as well as each side. Larger plates are screwed to the wall studs.

Bulkhead Plates are made for an individual application. In order to fabricate a pair of the Bulkheads, we will need digital photos of both sides of the wall, height of the holes, stud spacing, cable type and cable count. E-mail the information to the support link on the Home Page.

The Problem: A hospital's fire rated barrier day before a JACHO inspection.
The Solution: A pair of bulkhead plates for (3) 2" Split Sleeve Systems. A plate for each side of the wall that acts as the inside washer for our Split Sleeve Systems.
Apply a 3/8 bead of firestop caulk behind each plate
Pass the cables through the slots in the Bulkhead Plate and press against the wall on each side. 

(Large Bulkhead installations require the plates to be screwed to the wall studs for support.)
Install the (3) Split Sleeves. Refer to the UL System for the rating of the wall to determine the thickness of intumescent putty and if packing material should be used in the ends of the sleeves.
