Why Hydraulic Single Swing?

Head Room

The Single Swing Hydraulic System opens out fully, providing almost the entire rough opening height clear – Perfect for allowing large machinery into and out of a space or getting every inch of height possible out of a counter or bar top application.

Flexible Speed

The operating speed of the Single Swing System can be customized to best fit the design and use of the space while still maintaining the high safety standards expected of Crown Products.

Remote Power

The power unit may be located anywhere in the building, thereby providing customers with quieter operation and contributing to a cleaner look.

Flexible Sizes

From the smallest bar-top application to the largest storefront, the Single Swing system is available in a wide range of sizes. Maximum sizes are determined by calculations of width, height, and weight of the clad product.

All Steel Construction

Narrower steel profiles allow for more glass volume and greater visibility.


  • Shipped powder-coat finished. A full array of standard, non-standard, and custom colors are available, with few exceptions.
  • Manual lowering system in case of power failure
  • Total security without the use of locking mechanisms. The hydraulic cylinders draw the system panels closed with 1,000+ lbs. of force, creating a tight seal around the perimeter
  • Full perimeter weather seals
  • Integral mounting frame to limit loads on the structure
  • Remotely mounted power unit
  • No floor track is required. Nothing to impair movement through the opening
  • When open the system forms an awning providing protection from the weather and sun
  • The use of hydraulics eliminates the need for limit switches

Remote Operation

Remote Transmitters offer ease of entry upon approach. Transmitters are constant contact. For safety reasons, we require either photo eyes or a lead-edge sensor with remote transmitters.


For turn-key products, we offer our glass retainer system (glass stops) and a variety of dual or single pane glazing options. All factory-supplied glass is laminated for safety. Customers may also elect to provide a virtually unlimited number of inserts such as polycarbonate, steel or wood, to name just a few.

Crown Doors finishes each of our projects right here, in factory, using our state-of-the-art powder-coat facility, and our custom-design mantra follows through to our finish options as well – A full array of standard, non-standard, and custom colors are available, with few exceptions. We maintain a small list of customer-favorite colors as “standards,” though virtually any “non-standard” or entirely custom finish options are available (may affect cost and lead time).

Additionally, projects may be manufactured from stainless steel, available for corrosive environments (seaside or pool house installations). Stainless systems may be powder-coated as well.
