Climax Metal C-100 Shaft Collar, Zinc Plated Steel, Set Screw Style, One Piece, 1 Bore, 1-1/2 OD, 5/8 Wide, With 5/16-18 Set Screw

Its a chunk of metal with holes. Fits stock bar well.

Perfect

Low price for a quality part. As advertised. I am buying more.

Seems like a good quality of steel

Easy to install

Inside diameter was too small to fit 1 steel tubing.

I purchased one 1 inch ID (inside diameter) as a reference sample for future Purchases. Its lite weight. Brushed aluminum clean finish. set screw is iodized black finish. Smooth operation. Included are two Allen wrench/Allen key. I recommend this product.

Used for a shop made spinning drum to drag the lawn and make it level.

Very convenient, useful, reliable

Works great and for the price, its a great product!
