Universal Joint Adapter 19 mm for Screw Jack - Joint Attachment 130 mm
Product.Nr.: 990017665
- Makes it easier to screw caravan and trailer support legs in and out
- Universal joint enables work without constant bending down
- Fits 19 mm drive (cap and socket)
- Robust design in Black, compact and handy
This universal joint adapter for screw jacks (19 mm) is a practical aid when levelling and stabilising caravan, trailer or motorhome support legs. It is fitted between the tool/drive and the support leg and makes screwing the legs in and out noticeably easier.
The integrated universal joint (articulated joint for torque transmission at an angle) ensures you can work cleanly even when access to the support leg is awkward - e.g. with low mounting or limited clearance. This means less bending down is required and operation becomes more comfortable.
Ideal for camping, on the pitch or in the workshop: the adapter supports quick handling of screw jacks and contributes to a stable stance of the vehicle.

Frequently asked questions about this product
Three factors are key:
- Tube diameter — measured on the support wheel’s tube, not on the bracket. Common sizes are 35, 48 and 60 mm. It’s best to check with a calliper: a 48 mm support wheel won’t fit into a 60 mm bracket.
- Load capacity — this must match your trailer’s tongue load. A support wheel that is not strong enough will bend or become impossible to crank under load.
- Design — automatic jockey wheels fold in automatically when the trailer is coupled; basic models are cranked up by hand and locked into place.
Go straight to the right size: 48 mm jockey wheels, 60 mm jockey wheels or the full overview.
Common mistakes: ordering the wrong tube diameter; failing to crank the jockey wheel fully up or lock it in place before setting off; the clamp being too loose. A jockey wheel that spins freely can quickly cause damage on the motorway.
When it’s worth replacing: a worn-out wheel, a stiff crank, or a worn-out spindle. In most cases, a complete training wheel is cheaper than buying the parts separately.
