Description
The GU 9.35509 tilt & slide positioning keep is a critical component for the Gretsch-Unitas (GU) Tilt & Slide patio door hardware range. This part is specifically designed for the GU-966, GU-968, and GU-150 systems. It’s often referred to as a ‘positioning keep’ or ‘engaging striker’.
The primary function of a keep is to guide the door into the correct alignment as it transitions from the sliding position to the locking position. Over time, these keeps can suffer from wear and tear or stress fractures due to the heavy weight of double-glazed patio sashes. Replacing a worn striker ensures your door continues to operate smoothly, tilts correctly for ventilation, and locks securely.

FAQs
How do I know if I need a new positioning keep?
If your Tilt & Slide door is struggling to click into the upright tilt position, or if the bottom of the door feels loose when trying to close it, the positioning keep may be worn or cracked.
Is this part profile-specific?
While the GU 9.35509 is a standard hardware component, it’s designed to sit on specific profiles. Depending on your door frame (uPVC or timber), you may occasionally need to use a shim (or packer) underneath to ensure a flat, secure fit.
