Figure 4-8.—CWU-62/P antiexposure coverall. 3. Trim the wrist seals in the same way as the neck seal, except the trimming increments must not exceed one-third inch at a time. 4. After trimming the seals, have the aircrew member put on the coveralls to determine the seal restriction and the water-sealing characteristics. If any adjustments are necessary, you must repeat steps 1 through 3. SRU-2WP RUBBER SOCKS.– The SRU-25/P rubber socks are supplied in eight sizes. The rubber socks are one-piece and are molded to shape to provide comfort and a good fit. The tops of the socks extend above the flight boots to reduce bulk and restriction. The size of the SRU-25/P rubber socks will be governed by the size of the flight boot to be used. Usually, a rubber sock one size smaller than the boot to be used will provide an acceptable fit. The aircrew member should wear a pair of heavy wool socks, then put on a pair of SRU-25/P rubber socks corresponding to his normal boot size. The rubber socks should be worn in a slightly stretched condition to prevent wrinkles or bulk in the boot, but they must not be too tight. Larger or smaller rubber socks and/or boots may be required for a proper fit. To fit the rubber socks, select the correct size of rubber socks and fit them to the CWU-62/P coveralls as follows: 1. Have the aircrew member put on the antiexposure assembly (except the hood, mittens, and flight suit), the MA-2 torso harness, if applicable, and a pair of properly fitted, heavy wool socks. 2. Mark the coverall legs and socks (L and R) on the inside and front and back. This is to ensure the socks are matched to the correct leg during installation. 3. Have the aircrew member sit in a straight- back chair with his legs drawn back, heels directly below the kneecaps, and his feet flat on the floor. 4. Turn the top 2 inches of sock down, forming a temporary cuff. Mark the circum- ference of the coverall legs where they meet the 4-11
