Universal Ultra-Slim Scissor Mount for 49"-120" w/ACC-UCM3

Ideal Use Cases

The Peerless-AV SmartMount® STS680-1UCM3 Universal Ultra-Slim Scissor Wall Mount is designed for displays from 49 to 120 inches and loads up to 250 lb. Its wall-mount, tilt, and extendable functions fit UC/VC applications and recessed wall installations where access to equipment behind the screen is important. Corporate meeting environments, digital signage deployments, and hospitality spaces can use the slim 1.80-inch minimum adjustable depth to keep the installation close to the wall. When components need attention, the display can be pulled outward instead of remaining fixed at its installed depth.

Why Choose This Model

The defining advantage of the STS680-1UCM3 is its scissor-style extension. Its extendable adaptors allow a mounted display to move as far as 12.80 inches, or 325 mm, from the wall. The adaptors lock securely in place after installation or maintenance is completed. Tilt adjustment ranges from 0 to 15 degrees, adding positioning flexibility alongside rear access. Universal VESA compatibility supports varied display configurations, with listed mounting patterns including 200 x 100, 1000 x 400, and 1000 x 600. The combination of a 250 lb capacity and support for screens up to 120 inches addresses demanding large-display installations.

Installation and Integration

Peerless-AV equips the mount with its Hook-and-Hang™ feature to make installation quick and simple. An open-access design preserves wall-space flexibility for outlets and in-wall boxes, which is particularly useful in recessed installations and projects with equipment located behind the display. Assembly is required. The package includes one STS680 wall mount and one ACC-UCM3 component mount. The ACC-UCM3 allows AV components to be installed, configured, and cabled off-site before it is quickly attached to the display mount, reducing work required at the installation location. The mount measures 40.20 inches wide, 28.30 inches high, and 12.80 inches deep.

Performance Highlights

The STS680-1UCM3 provides a minimum adjustable depth of 1.80 inches and a maximum adjustable depth of 12.80 inches, combining an ultra-slim resting position with service access when extended. It supports displays and digital signage displays weighing up to 250 lb. The black mount has a fused epoxy finish and is identified as scratch resistant and tamper resistant. It is UL Listed, TAA compliant, and compliant with the Restriction of Hazardous Substances standard. Peerless-AV also covers the model with a lifetime limited warranty, supporting its use in long-term corporate, hospitality, and digital signage projects.

What Makes It Different

• Included component mounting: The kit incorporates one ACC-UCM3 component mount rather than supplying only the display-mounting structure.
• Off-site preparation: Components can be installed, configured, and cabled away from the job site before the ACC-UCM3 is attached to the mount.
• Extended rear access: The scissor mechanism brings the display up to 12.80 inches from the wall and locks securely after work is completed.
• Low-profile positioning: A 1.80-inch minimum adjustable depth keeps the display close to the mounting surface when extension is not needed.
• Flexible wall integration: The open-access design provides space flexibility for outlets and in-wall boxes, while Hook-and-Hang simplifies the mounting process.
• Large-display support: The universal, VESA-compatible design accommodates 49- to 120-inch displays with a maximum load capacity of 250 lb.

Final Assessment

The Peerless-AV STS680-1UCM3 is well suited to installations that require a slim display position, adjustable tilt, and practical access to components behind a large screen. Its 12.80-inch maximum depth, locking extendable adaptors, universal VESA compatibility, and included ACC-UCM3 component mount directly address installation and maintenance needs. For UC/VC rooms, recessed wall projects, corporate displays, digital signage, or hospitality applications, it combines large-screen capacity with an integration-focused mounting design.
