Kirk LBA-1 USB/AC spacer block

Kirk LBA-1 USB/AC Spacer Block, more space for your cables

You know the situation: you want to align your camera perfectly in portrait orientation on the tripod, you’re using a Kirk L-bracket, you plug in a USB cable or the power supply, and that’s exactly when everything collides. The Kirk LBA-1 USB/AC spacer block solves exactly this problem, in a pretty elegant way and without much fuss. It creates the necessary distance between camera and L-bracket so that USB and AC plugs sit cleanly without jamming, bending, or constantly getting in the way.

With this spacer you can use your camera in portrait orientation while it is simultaneously connected via USB cable to the computer or to an external power supply. The plugs get the space they need, and the cables are neatly routed through a side opening. No fiddling, no “it’ll somehow fit”, but a stable, repeatable solution that simply works in everyday studio use or during tethered shooting.

Compatible with all Kirk L-brackets, one solution for your entire setup

The Kirk LBA-1 USB/AC spacer block is designed to fit all Kirk L-brackets. So if you’ve already invested in the Kirk system, you don’t have to think long about whether this part is compatible. It integrates seamlessly into your existing Kirk L-bracket setup and expands it with a very practical function: more space for your ports without ruining the form factor of the bracket.

Installation is pleasantly straightforward. The spacer is attached directly to the L-bracket with two hex socket screws. It sits securely, doesn’t wobble, and can also be removed again if necessary without you needing a full workshop. A standard hex key is enough. This way you can flexibly adapt your tripod setup depending on whether you’re currently working with cables or prefer to go completely “clean”.

Solid construction, made in the USA

The Kirk LBA-1 USB/AC spacer block is made from 6061T6 aluminum, a high-quality, field-proven aluminum that offers a very good weight-to-strength ratio. In addition, there are stainless steel screws that ensure a durable, corrosion-resistant connection. The result is a small but extremely robust accessory that easily copes with tough studio or outdoor use.

Weighing only 100 g, the spacer remains pleasantly light. It doesn’t add unnecessary bulk, hardly changes your camera’s balance on the tripod, and can be easily carried in a backpack or studio bag. Yet it feels high-quality, not like some wobbly adapter that you’ll want to replace after two uses.

Mount permanently or remove quickly, the choice is yours

You can leave the Kirk LBA-1 USB/AC spacer block permanently on the camera or on the L-bracket. For many, this is the most convenient solution: camera on the tripod, plug in the cable, done. Especially during tethered shooting in the studio, during longer sessions, or when working with external power, it’s nice not to have to rebuild everything each time.

If you don’t need it at some point, it can be removed just as easily. With a few turns of the hex socket screws, the spacer is unscrewed and you use your Kirk L-bracket again in the classic way, without additional spacing. This flexibility also makes the spacer block interesting for photographers who switch back and forth between outdoor shoots, studio work, and video setups.

Optimized for USB and AC connections, more freedom in portrait orientation

The real trick of the Kirk LBA-1 USB/AC spacer block: it specifically creates space for USB plugs and AC plugs that would otherwise bump into the L-bracket. Especially modern cameras with side ports quickly reach their limits in portrait orientation when a bracket is mounted. The spacer shifts the L-bracket slightly outward so that the plugs can be inserted cleanly and the cables are not pinched.

The cables are routed through a side opening, which not only looks tidier but also reduces the strain on the ports. Less pull, less bending, less risk of intermittent contact. This clean cable routing really pays off during continuous operation, for example in long-term shoots, product photography, or streaming.

For studio, tethering, and video, a small part with a big impact

Whether you’re shooting directly into the computer in the studio, running your camera for longer periods with an AC power supply, or relying on a stable connection when filming: the Kirk LBA-1 USB/AC spacer block ensures that your ports remain easily accessible. You can align your camera in portrait orientation on the tripod without having to wonder each time whether the cable is going to bump into something again.

Especially if you work professionally or are just tired of wobbly makeshift solutions, this spacer is a surprisingly simple yet effective addition. It doesn’t make creative decisions for you, but it clears the way so you can focus on what really matters: the image.
