Twin truck dollies perfect for moving organs or upright pianos, as well as appliances and heavy shop machinery. Manufactured by JET Equipment Co. Wood and Steel Construction. 2 Ratchet Straps Included – I used ratchet straps with these, and they worked perfectly! If desired, new felt will need to be applied to 3 of the 4 uprights. Some light usage marks and scratches – These were very lightly used and well taken care of… I simply have no use for them anymore. They are both in 100% functional, tight, fluid, stong and sturdy condition! Please see pictures for further details and descriptions. Feel free to ask any questions you may have.
