Built with rock-solid tuning stability in mind, the Pearl CL250 Bridge Lug employs a floating brass swivel nut for a more secure thread hold and superior shell tone, in combination with nylon shell isolators. The low-contact look of the CL Bridge Lug utilizes brass inserts for each Stainless Steel tension rod, further increasing tuning stability, and the classic design gives the shell a classic, sophisticated aesthetic edge, and the perfect kind of contact for incredible vibration control.
