These high-quality, hydraulic hinge-closer units provide a concealed finish, a highly adjustable self-closing function and burglary and vandalism resistance. When closed, the SureClose® CONCEALFIT system cannot be seen or tampered with.  SureClose® CONCEALFIT features ‘Final Snap-Close Action’, which increases speed at the end of closing to ensure latching and to overcome electric or coded locks. Designed to never leak hydraulic fluid, the SureClose® CONCEALFIT technology is extremely safe and will not present resistance if closed quickly in an emergency. SureClose® CONCEALFIT is suitable for pool and safety gates*. With NO hold-open feature, it opens to, and self-closes from, 125˚.
