Galvanized Finish: on footpiece, guides, brackets and barrel
Safety Bearing: This unique safety device functions as both a bearing and inertia brake for motorized service doors and grilles. The safety bearing is designed to prevent the curtain from free-falling if there is damage to or failure of the motor operator, drive chain or spring assembly. If a malfunction occurs and the downward speed increases to an unsafe rate, the inertia brake absorbs the added energy and safely stops the load.
Powdercoat Finish: a durable and decorative finish for steel or aluminum surfaces. It provides longer life and requires less maintenance than a standard finish. Powder coating is available in a variety of colors for use on many products. Consult factory for color selection, applications and limitations.
