Item 3. Steel Brace Rail 2” by 7’ (Quantity 412)

Steel Brace Rail: Shall be a minimum of 7’in length not to exceed 8’ in length, singular piece of round tubular steel constructed with a minimum 1-7/8” outside diameter, by minimum 11-gauge wall thickness. Brace rail ends shall be pressed flat on both ends and be equipped with both a 90- and 45-degree angle capable of being mounted both horizontally as well as diagonally on all bracing structures. Brace banding shall be 2-7/8” heavy duty galvanized brace band, measuring 1” wide by minimum 1/8” wall thickness and supplied with 3/8” galvanized grade five (5) carriage bolts, 1-1/2” to 2” in length with grade five (5) galvanized flange nuts.

Item 4. Drill Stem Mechanical Gate Closer (Quantity 44)

Gate Closer: A36 rolled round steel bar 3/16” to 5/16” diameter or adjustable minimum

3/16” diameter galvanized steel cable wire loop with a minimum Working Load Limit

(WLL) 840 lb. force and Minimum Breaking Load (MBL) 4200 lb. force, fastened to a cam lever device. The pipe cover shall be constructed of a minimum 11-gauge steel plating made to rest upon and exceed the diameter of the 2-7/8” steel brace post.

The mechanical break over latch shall be attached to a minimum of 2-3/8” (OD) by 11-gauge minimum wall thickness tubular steel stem that slides securely into the 2-7/8”

(OD) steel brace post a minimum of 6”. The steel stem shall be radiation free (<12 µR/hr.). The closer must be capable of fitting over a maximum 4” diameter wood gate stay and securely holding the gate stay in place. Alternatives require prior approval by the Contracting Officer (CO) with submission of samples.

Item 5. Gate Loop (Quantity 140)

Gate Loop: A minimum 3/16” diameter galvanized steel cable wire loop with a minimum Working Load Limit (WLL) 840 lb.-force and Minimum Breaking Load

(MBL) 4200 lb. force, attached to a 3” U-bolt muffler clamp assembly and shaped so a maximum 4” diameter gate stay will be securely held in place. The muffler clamp shall be secured to the steel brace post with 9/16” grade five (5) galvanized round U-bolt and galvanized flange nuts. A sleeve shall be welded to the muffler clamp, parallel to a leg of the U-bolt. Another sleeve shall be welded parallel to the other leg of the U-bolt, on the same face of the muffler clamp. The sleeve shall be large enough to allow free movement of the steel galvanized cable but small enough to keep terminated ends from passing through when the loop is under pressure. The galvanized steel cable shall be threaded through the sleeves to form a loop without a bind and the ends shall be crimped with a flattened 9/16” grade five (5) galvanized nut further secured by a weld. Alternatives require prior approval by the CO with submission of samples.
