Really Right Stuff BH-PF40 platform: mounting plate for BH-40

Really Right Stuff BH-PF40 platform for BH-40 ball head

Sometimes less is simply more. If you very deliberately want to use your Really Right Stuff BH-40 ball head without a quick-release system, the BH-PF40 platform comes into play – a simple mounting plate that does exactly what it’s supposed to do: hold reliably, center cleanly, and stay out of your way while you work.

The BH-PF40 platform is specially designed for the BH-40 ball head and provides a direct, play-free connection between ball head and camera or accessories. No unnecessary frills, no wobbly adapters, just a solid, precisely machined base that integrates seamlessly into demanding setups.

Mounting plate for BH-40 with 1/4 inch mounting stud

The core of the BH-PF40 platform is the integrated 1/4 inch mounting stud with 1/4"-20 thread. This standard size fits a wide range of cameras, plates, and specialized mounts, allowing you to use the mounting plate very flexibly. The mounting stud is firmly integrated into the platform, ensuring a stable, twist-proof connection.

Especially if you frequently work with heavier setups, such as telephoto lenses or compact video rigs, this solid 1/4"-20 mount really pays off. You screw your equipment directly onto the mounting plate, tighten it securely, and have a robust, direct connection without additional quick-release components that would unnecessarily increase the system height or introduce potential points of failure.

Lock nut and 3 set screws for maximum security

The BH-PF40 platform comes with a matching lock nut and three set screws. The lock nut serves to additionally secure the 1/4 inch mounting stud so that nothing can unintentionally loosen under load. This extra safeguard is a noticeable advantage, especially during longer sessions, with vibrations, or with frequent panning.

The three set screws allow you to secure the platform even more firmly on the BH-40 ball head. You can adjust them so that the platform can practically no longer rotate. This is particularly interesting when you’re working with repeatable framing, panoramas, or precise studio setups where every small movement would be visible. It’s a small detail, but details like this are what make a setup reliable in the long run.

Made in the USA, precise manufacturing and high-quality materials

The BH-PF40 platform is manufactured in the USA and therefore follows the high quality standards for which Really Right Stuff is known. The components are precisely machined, the edges are cleanly finished, and the fit is exactly what you would expect from professional photo accessories. No play, no rattling.

Thanks to careful material selection and precise manufacturing, the surface is durable and built for tough everyday photographic use. Whether in the studio, on location, or outdoors in changing weather conditions, the platform remains dimensionally stable and reliable. It may look like a small part at first glance, but anyone who regularly works with ball heads quickly notices how pleasant it is when components like this simply work.

Technical data: compact, lightweight, and stable

The BH-PF40 platform is deliberately kept compact so that it doesn’t unnecessarily increase the size of the BH-40 ball head and your setup stays streamlined. All relevant dimensions at a glance, without leaving anything out:

• Diameter: 44 mm – a comfortably handy size that suits the BH-40 well and provides sufficient contact area.
• Weight: 25 g – very light, so your overall setup is hardly burdened any further.
• Height: approx. 13 mm – the platform only adds a moderate amount of height, allowing for a low, stable mounting.
• Platform thickness: approx. 11 mm – solid material thickness for a robust, torsion-resistant base.

This combination of compact dimensions and low weight makes the BH-PF40 platform an unobtrusive yet important component in the system. It’s there where you need it, without drawing attention to itself.

Direct mounting without quick-release system

If you deliberately want to use your BH-40 ball head without a quick-release system, this platform is designed precisely for that purpose. You mount the BH-PF40 plate directly on the ball head and then attach your camera or accessories via the 1/4"-20 mounting stud. This creates a direct connection without additional clamps or rails.

This can be particularly useful when you want as few components in the system as possible, for example for long exposures, macro shots, or applications where every additional interface could potentially introduce play or vibrations. The BH-PF40 platform reduces the system to the essentials and helps you create a clear, stable base.

Areas of use and typical applications

The BH-PF40 platform is suitable for photographers and filmmakers who want to configure their Really Right Stuff BH-40 ball head flexibly. You can use it, for example, when you:

• want to create a fixed, permanent connection between the ball head and a specific camera or special housing,
• want to work without a quick-release plate in order to reduce the overall height,
• prefer a minimalist setup in which every part has a clear function,
• are building studio or repro setups where absolute stability is more important than rapid changes.

In such scenarios, the BH-PF40 mounting plate plays to its strengths: easy handling, clear function, robust construction. Nothing spectacular, but very reliable.

Compatibility with the Really Right Stuff BH-40 ball head

The platform is specifically designed for the Really Right Stuff BH-40 ball head. Its shape, diameter, and height match this model exactly and complement the ball head as an optional accessory. If you already use a BH-40 and are looking for a way to operate it without a quick-release system, the BH-PF40 platform is the right solution.

Thanks to precise manufacturing, the mounting plate sits cleanly on the ball head, and you can additionally secure the connection with the three set screws. This creates a closed system of ball head and platform that remains stable even with frequent use.
