CENTER MOUNTING

MAINTENANCE REQUIREMENTS

• Gate stop must be installed when using SF models. Gate must not be allowed to open past 90

. Doing so voids warranty.

• Never use more than two (2) SureClose hinge/closers on any one gate.

• Remove all other types of hinges and self-closing devices.

• Always install SM hinge at bottom of gate and 57 or 108 closer on top.

• Ensure the gate does not swing through the line of the fence. Use a “gate stop” or a latch (with striker)

to prevent this.

• All steel mounting brackets (gate and post) should be painted or powder coated. Spray painting is recommended.

• The anodized aluminum mounting brackets do not need finishing, but they may be painted or powder coated.
• DO NOT powder coat the hinge/closer, but they may be painted.

• DO NOT unscrew nozzle past the surface of the body.

• DO NOT turn the adjustment nozzles more than two (2) full rotations.

• DO NOT remove the adjustment nozzles or disassemble these hinges at any time. Doing so voids warranty.

• Ensure the hinges are kept free of sand, ice and other debris that could impair effective operation.
