I have the JMI Losmandy G11 Wheely bars that fit the Losmandy G11 tripod and lots of other models. I have personally used a G11, Meade 12" LX200 tripod, and a 10" Particle Wave Monolith Pier on them with no problem. The benefit to this model is the raised edge on each leg to help keep the tripod securely in place. I have had over 300lbs plus on them with no problem. The are USED but in very good condition. New these run $260 plus $20 shipping from JMI. I am only asking $150 plus shipping ($20.) This is your chance to save OVER $100 from new if you don't mind used.
I prefer Paypal.
