The LiftMaster 658302 Edge Pneumatic 2‑Wire 22 ft. Air Hose is a replacement pneumatic sensing edge hose designed for LiftMaster gate and commercial door safety systems. When mounted along the leading edge of a sliding or swing gate, vertical lift gate, or rolling/sectional door, the hose compresses on contact to create air pressure that triggers a compatible air switch, signaling the operator to stop and reverse. This helps provide entrapment protection as part of a compliant system when properly integrated with the operator’s safety inputs. The 2‑wire configuration is intended for a simple dry-contact connection through the appropriate LiftMaster or compatible interface.
Ideal for new installs or upgrades, this hose is commonly used in residential and commercial applications where a pneumatic safety edge is specified. Installation typically involves securing the hose in an edge retainer, connecting it to a compatible air switch, and wiring the 2‑wire lead to the operator’s safety terminals per the operator manual and local codes. After installation, perform functional testing and routine checks to verify obstacle detection and reversal. Use only with compatible LiftMaster controls and interfaces designed for pneumatic sensing edges, and have installation and adjustments performed by a qualified technician.
