Up to 7mm thick conforming to ETRTO Standards built to our requirements.
Rolled from 50 x 12mm (SPECIFICATION) steel continuously machine welded into them using a special process to provide the anchor for the clamps and to reinforce the rim.
Up to 6mm thick are rolled with a double rib for additional strength and a precise concentric fit into the tapered bead section of the tractor wheel.
Drop forged Carbon Steel hardened and tempered to BS970 with a tensile strength up to 700 Nmm2.
The design of clamp means easy fitting to fixed centre wheels – simply attach eyenuts to existing wheel weight holes. A unique removable spacer allows the clamps to work correctly either in this position, or attached to adjustable wheel rim bolts.
Threaded Rod & Hookends
Our threaded rod is no ordinary rod, made from high tensile steel with a specific pitch of 2.5 to ensure both durability and strength, whilst our hookends conform to BS970 containing 1% Chromium Alloy Steel hardened and tempered to 215/255 BHN with a tensile strength over 870 Nmm2.
Our standard range of Stocks Duals are the strongest dual wheel available and feature heavy-duty clamps, hooks, eyenuts and eyebolts.
There is no need to rotate the dual for alignment with the tractor wheel. Wherever the eyenuts are attached to the tractor wheel, simply fit a hook to the eye nut and an over centre clamp to the dual wheel power rail, and tension with the handle supplied.
