LOT OF 2 FIRESTIK K-4A CB ANTENNA HEAVY DUTY SO-239 STUD MOUNT - Bulk

In this review the reviewer examines a practical bulk pack for CB enthusiasts: a lot of two FireStik K-4A heavy duty SO-239 stud mounts. The bottom line is straightforward - this pair is for anyone who needs reliable, no-frills CB antenna stud mounts that fit any 1/2' hole and standard 3/8' x 24 thread. The reviewer found these mounts best when replacing worn studs or outfitting multiple vehicles or installations at once, and appreciates the simple, heavy duty construction and compatibility with all FireStik antennas and mounts.

Key Features

• Fits any 1/2' hole: Makes installation easy in common mounting plates and brackets without extra drilling or modification.
• 3/8' x 24 thread: Matches the standard thread used by most CB antennas for a secure, vibration-resistant connection.
• Heavy duty SO-239 stud: Built to withstand road and marine conditions where a sturdy mount matters for signal stability.
• Fits all FireStik antennas and mounts: Ensures compatibility across the FireStik lineup so users can mix and match antennas and bases.
• Bulk item, quantity of 2: Provides a spare or a second mount for dual-vehicle setups without retail packaging.

Who It's For

This product is aimed at CB radio owners, installers, and fleet operators who need a dependable replacement stud or an extra mount for another vehicle. The lot of two is convenient for hobbyists who keep spares on hand, or for small shops that service multiple rigs and prefer buying mounts in pairs.

Those who want a packaged retail presentation, color-matched cosmetic parts, or an all-in-one antenna kit should look elsewhere, since this is a bulk item sold without retail packaging and focused solely on function rather than presentation.

Pros & Cons
