Defender Security® U 9809 Sliding Window Lock, White, Painted

This sliding window lock is constructed of die cast and comes in a white painted finish. This lock is designed for use on horizontal vinyl sliding windows, yet it may also work with some vertical sliding (single hung) windows, depending upon the-type of vinyl liners and balances used to construct the windows. Note: these locks will fit most all horizontal vinyl sliding Windows and some vertical sliding windows, but not all of them. These locks feature an adjustable jaw that has a vise-like grip and they are capable of opening up to 1/2 in wide for a secure, non-marring hold on thick vinyl rails. When installing this lock, the cam-style locking lever should be rotated hand-tight over the rail or vinyl edge to a sufficient torque prior to locking down the lever. Can be adjusted to fit on rail thicknesses ranging from 1/16 in to 1/2 in thick. Used as a secondary lock when window is shut and to secure the Windows during ventilation. For a larger version of this lock (used on vinyl frame patio sliding doors) see PRIME-LINE® part U 10547. No tools are required for installation.
