Overview
A pressure mounted steel walk-thru dog gate that expands from 29.5 to 38 inches wide, with an auto-close spring-loaded door and two included 3 inch extensions.
This is a pressure mount gate rather than a hardware mounted one, relying on tension against the door frame instead of screws into the wall. The auto-close door with a spring-loaded latch lets someone walk through without holding the gate open manually, the main functional difference from a simple panel gate. The two included 3 inch extensions push the maximum width from 35 up to 38 inches for wider openings.
- Expands 29.5 to 38 inches wide
- Auto-close spring-loaded door
- Steel frame construction
- Two 3 inch extensions included
Who it's for
Owners needing to block a doorway or stairway opening between roughly 29.5 and 38 inches wide without drilling into walls. Not suited for openings wider than that range even with the extensions, or for households wanting a permanently mounted gate.
Strengths and trade-offs
Drawn from this product's published specifications.
- Auto-close door with spring-loaded latch, no manual closing needed
- Pressure mount install requires no wall drilling
- Two 3 inch extensions included for wider openings
- Steel construction rather than plastic
- Pressure mount may not suit uneven or delicate door frames
- Maximum width caps at 38 inches even with extensions
Performance notes
The steel frame and pressure mount system hold the gate in place through tension rather than fasteners, and the spring-loaded latch closes the door automatically after each pass through. At 14.7 pounds, the gate carries enough weight for a metal construction while still being installed and removed without tools beyond adjusting the pressure mount.
