Installation and setup

Designed for ease of installation, the dual joist plate eliminates the need to locate a single central stud, speeding up mounting in spaces with parallel joists. The built-in lateral shift feature provides fine-tuning capability after the mount is secured, ensuring the display is perfectly centered without requiring repositioning of the entire assembly. Internal cable routing further streamlines setup by keeping wiring organized and out of sight.

It works well in educational settings, corporate meeting rooms, retail locations, and auditoriums where heavy AV equipment must be securely mounted across multiple joists. Its certifications and security features also make it a strong choice for government and enterprise installations requiring compliance and theft deterrence.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
