Sleeve block S-QTQT

A four-way, heavy-duty steel sleeve block for use with our S-QTQT Tower. Can be attached with S-RTW truss or S-RTD truss via our S-MT-Q-03 Forks set.
Its unique, spring-loaded wheel system allows for inclination of the sleeve block when deflection is experienced with longer truss spans. Its mechanical safety lock system secures the block from drop and lift, and a self-standing steel frame prevents damage to its locking system.
