The Mini can be used on any caravan up to 3500kg and has a lift height of 500mm.

Why would I buy a Mini?

The Mini is an entry level Black Jack with a big heart. If these things are important to you, buy it.

1. I like the lower price point at RRP $375.
2. My caravan\trailer has an existing 50mm jockey wheel clamp so the Mini will fit straight in, and after that it is permanently mounted.
3. It has 3 mounting positions so I can easily adjust it to suit.
4. My caravan\trailer is toward the lighter end, say 2,000-3500kg with a tow ball weight of 200-350kg.
5. The real estate in the A frame is tight or crowded, so it may not be possible to fit the Black Jack Clamp necessary to mount the Master and Maxi.

Black Jack Master

The most recent addition to the Black Jack product line is the Black Jack Master. This jack requires the use of the included Black Jack Clamp Bracket and has been developed with the Black Jack Safe Auto Stop. The Master can be used on any caravan up to 4000kg and has a lift height of 650mm.

Key Features and Included Accessories

Brute Strength: The Master has a lifting capacity of 1600kg, meaning it has more than enough strength for any caravan or trailer up to 4000kg. Simple to Install: The Master includes the Patented Black Jack Clamp Bracket, enabling simple installation. 3-Year Warranty: All Black Jack products—including the Master, its accessories, and spare parts—are backed by a full 3-year warranty from the date of purchase. Included in the Box:

• Black Jack Master with Safe Auto Stop
• Patented Black Jack Clamp Bracket
• Black Jack Folding Foot
• Black Jack All Weather Cover for extra protection against the sun and the elements
• Black Jack Foot Pad to prevent sinking in softer terrain
• Manual Handle, as a backup in case of loss of power.

  Why would I buy a Master?

  The Master is a mid-range Black Jack with almost all the features. If these things are important to you, buy it.
  1. I like the lower price point of the Master v the Maxi ($525 v $635).
  2. I don’t need the remote control, ball bearing worm drive and extra lift capacity the Maxi offers.
  3. My caravan\trailer is a good size, say 3,000-4000kg with a tow ball weight of 250-400kg.
  4. I have room to install the Black Jack Clamp on my chassis A frame.
  5. I really like the folding foot option that comes with the Master

The Maxi is the full featured Black Jack with all the fruit. When you want the best, buy the best.
