Redman CB Ham Radio Cobra Galaxy Mounting Black 5mm Knobs - Set of 4 | Durable Replacement Knobs for CB Radio, Ham Radio & Communication Equipment | Perfect for DIY Repairs, Upgrades & Custom Installations

These fit my Stryker 955HP with no issues. Tops are nice and wide, with a slot built in should you want to use a rather large slotted screwdriver and/or knife? Metal portion appears to be brass and sturdy. Buy with confidence!
