Option B the cylinder is removable; Option 6 is
environmentally resistant. For combination locks or
other options and grades see ASTM F 883.
**************************************************************************
Padlocks shall conform to ASTM F 883, Type [PO1] [_____], Option[s] [A, B,
and G] [_____] [and] [_____], Grade [6] [_____]. [EPB], Size 44 mm (1-3/4

GATE OPERATOR
Electric gate operators for sliding gates shall be as follows: Electrical
gate operators shall have a right angle gearhead instantly reversing motor
with magnetic drum-type brake, friction disc clutch, reversing starter with
thermal overload protection, and a chain-driven geared rotary-type
automatic limit switch. Gears shall consist of a hardened steel machine
cut worm and mating bronze gear. All gears and bearings shall operate in a
bath of oil. Gate operators with V-belt pulleys will not be allowed. Gate
operators shall be equipped with an emergency release to allow the gate to
be operated manually. The emergency release mechanism shall be capable of
being locked in the engaged or disengaged position. Positive stops shall
be provided on the gate tracks as a backup to the limit switches.
2.11
ELECTRO-MECHANICAL LOCKS
Electro-mechanical locking devices for sliding gates and personnel gates
shall be solenoid actuated such that the deadbolt retracts when the
solenoid is energized and remains electrically retracted until the gate is
closed. The solenoid shall be the continuous duty type, rated for 120V ac,
60Hz operation. The locking device shall be unlockable by key and shall be
keyed on both sides. Status of the electro-mechanical lock shall be
monitored by two limit switches (integral to the locking device) wired in
series. One switch shall monitor the deadlock lever and the other switch
shall monitor the locking tongue.

INSTALLATION
**************************************************************************
NOTE: For farm style fence, the layout will be
shown and will include fence section, height, mesh
size, locations of straight-line and corner-post
bracing, types and locations of gates, and gate
sizes. Drawings will also indicate the extent of
clearing required. Fences will not be located
adjacent to natural or man-made terrain features
that could provide easy access across the fence.
The graded fence line will be indicated on the
drawings where required.
**************************************************************************
Fence shall be installed to the lines and grades indicated. The area on
either side of the fence line shall be cleared to the extent indicated.
Line posts shall be spaced equidistant at intervals not exceeding 3 m (10
feet) 10 feet. Terminal (corner, gate, and pull) posts shall be set at
abrupt changes in vertical and horizontal alignment. Fabric shall be
