Gibraltar SC-GR-4L-C Ludwig Style Throw Off Drum Hardware - Compatible with Beaded Shells | Perfect for Drum Kits & Snare Drum Upgrades

As the title states, this throw off will bolt right up to an older 60's Keystone badged Ludwig Supraphonic. I used the original screws and didn't have to drill the shell. The mechanism was sticking out of the box. I have white lithium grease arriving soon, In the meantime I used a Q-tip soaked in olive oil to lubricate the mechanism. It works great now.Gibraltar makes good stuff. I have one of their hi hat stands and it's functionally as good as my mid range Yamaha Hi hat stand.
