Ursa Wings give you the versatility you need to do the job right. The patented design encloses, heightens, or widens any Ursa Cargo Sled. The wing hinges easily attach to the Cargo Sled with four bolts. Each wing has two heavy-duty metal fittings molded into its base. The wings are held in position by milled alloy locking pins that insert into the hinge and metal fittings to lock the wings into position. For ultimate flexibility, the wings position independently of each other. Configure the Ursa Wings in whatever way fits the job at hand — closed, open vertical, open flat, or any combination. The optional Wing End Panels connect the wing edges in the open vertical position. The durable all-weather fabric panels stabilize Ursa's expanded cargo space, and provide handy storage pockets for tools and wagon accessories. Wings Closed In this position, the Ursa Wings close to protect your load from weather. Wings Open Vertical In this position, the Ursa Wings double the cargo capacity of the sled to more than 10 cubic feet. Wings Open Flat In this position, the Ursa Wings give you a wider platform for carrying awkward items, such as fallen branches or wood planks.
