Intromark PP-1-GRN Door Lock .68 lb Green 1-Pack

Sliding Glass Door & Window Accessory

The Intromark PP-1-GRN is a green visual marker and lock designed for sliding glass doors and windows. It helps prevent accidental collisions by making the glass more visible while also functioning as a security device. The accessory secures partially open doors to prevent further opening and can assist parents with child safety. It weighs .68 lb and comes as a single unit.

Suction Cup Attachment

The deciding specification is the suction cup backing which requires no installation tools or permanent fixtures. You simply press the heavy-duty PVC unit onto the glass surface to engage the lock or marker function. This mounting method allows immediate use on any smooth glass pane without drilling or adhesives. The lock engages once suctioned to secure the door position effectively.

Tool-Free Setup & Limits

Installation takes seconds because the suction cup attaches directly to clean glass with hand pressure. What usually goes wrong is a loss of grip if the glass surface is dirty, wet, or textured, causing the unit to detach unexpectedly. Extreme temperature changes can also reduce suction reliability over time. Regular cleaning of the cup and glass maintains consistent holding power for safety and security.
