TM 55-07/NAVSEA OP 3221 Rev 2
(2) A-frames may be used to secure stowage that ends in an area of a hold where there is no permanent
ship's bulkhead to support an end bulkhead. Figure 7-15 illustrates the construction technique for such a bulkhead. The
hatch coaming and deck are used as support points for 4by 4-inch main braces. Kickers provide the required bracing of
the uprights. Braces and kickers are constructed of 4by 4-inch stock, cut-to-fit. The structure should be securely laced
with 2by 3-inch lumber; cleats under the kickers are 2by 4-inch material.
