Item Summary

This SureClose Flush Mount Screw-On Kit comes with: 1-SM AT90 S and 1-57SF AT90 S hinge and 2-7515 brackets

This hinge combination will self-close a 90 lb. gate

This hinge combination will self close from 90° and has a max gate swing of 90°.

The “SF” Model SureClose hinge/closers are designed for child/ pool safety, they do not have a hold-open feature and they are not meant to be propped open.

SureClose hydraulic closers and hinges deliver a revolutionary option for heavier gates up to 1,500 pounds that call for more advanced closing. The small footprint on the fencepost makes the SureClose an attractive option for a more refined look. The hydraulic closing mechanism is adjustable for closing speed. SureClose is precision engineered with ball bearings to ensure long life, and the hydraulics in the closer are guaranteed against leakage or failure. Ideal for commercial, industrial, residential and ornamental applications.
