I didn't use these because a friend had another set he gave me after I bought these.
"These extremely rugged thermoplastic knobs are an exact match for the knobs on the wedge sides and tripod legs. While they look the same, the similarity ends there. They are many times stronger than the original brittle "bakelite" type knobs. The tripod knobs are smaller than stock as a feature, that way they are less likely to catch on a doorway or shoelace, and you are less likely to exert a damaging force to the tripod legs. These are only sold in sets, replace all of them and be done with it! They are also a perfect match for the ScopeTronix deluxe latitude adjuster."
IMPORTANT NOTE: Some of the later LX200's use a shorter screw bolt measuring approximately 1/2 inch. The knobs for sale have a bolt which measures 7/8ths of an inch from one end of the silver to the other end of the silver. If you are interested in buying, please measure your current Tripod Knob screw bolt to ensure it is roughly 7/8th's of an inch long.
Bought new these cost $29.95 including shipping. I am selling for $22 including shipping in the continental US - over 25% savings. I accept Paypal Cash (no credit card) payments, USPS money order, or cashier's check.
