Clear Sliding Door Lock & Marker
The Intromark PP-1-CLR is a transparent safety device for sliding glass doors and windows. It attaches with a suction cup so no tools or permanent installation are required. The heavy-duty PVC construction acts as both a visual alert to prevent collisions and a physical lock that secures the panel in place.
Fits Any Smooth Glass Without Tools
The suction-cup backing grips clean glass instantly and can be repositioned in seconds. It needs no screws, adhesives or frame modifications, leaving the surrounding trim untouched. Once applied it holds a partially opened door at a fixed gap, freeing the user from worrying about the panel sliding further.
Replaces Stick-On Decals & Fixed Latches
Unlike static decals it provides an actual mechanical stop, and unlike screw-in latches it leaves no holes when removed. The upgrade makes sense for renters, seasonal homes or households with children who need a temporary but reliable barrier that also serves as a grab handle.

Questions about this item
Does the suction cup lose grip after hours of continuous attachment?
The heavy-duty PVC body and suction-cup backing are designed to hold the door or window in place for extended periods, functioning as a visual marker, lock and third handle without permanent installation.
Does the lock generate any noise, heat or power draw while in use all day?
No — the device has no motor, electronics or battery, so it operates silently, produces no heat and consumes zero power while securing a sliding door or window.
What type of glass surface must I already have for this lock to work?
A clean, smooth sliding-glass door or window pane is required; the suction cup adheres directly to the glass without tools, screws or additional hardware.
