The Chain Glide^® 2 (patent pending) technology features an enclosed in-line chain for superior reliability and strength.

• Quieter: the enclosed in-line chain does not rattle around like an open chain drive rail providing quieter operation.
  
• Low Maintenance: no tensioning or lubrication of the chain is required for the standard life of the opener.
  
• No Mess: no greasy chains or wires exposed!  The aluminum rail has channels to conceal the chain and wire leads for a cleaner more attractive appearance.
  
• Long Life: reinforced metal drive sprocket provides longer life and minimal wear on the system.
  
• Performance: reliable performance even in extreme temperatures.
  
•  Safety: comprehensive six-part Safe-T-Beams^® meets or exceeds all UL, state, federal and CSA regulations, and incorporates an auto reversing system and LED diagnostics.
  
• Security: Genie^® Intellicode^® technology prevents unauthorized persons from opening your garage door by automatically changing the access code every time you use it.
