The B-tech SYSTEM X - joining plankit is a specialized joining plate designed for the B-Tech SYSTEM X modular speaker mounting system. Its primary function is to securely connect the BT8390 horizontal mounting rails to the BT8380 vertical support columns, enabling the assembly of the SYSTEM X freestanding speaker stands and other configurations that require extended or linked rail setups.

Key Features:

• Compatibility: Specifically engineered to fit the BT8390 rails with the BT8380 support columns within the SYSTEM X range.
• Material: Constructed from robust materials suited for durable speaker mounting (likely steel).
• Design: The plate acts as a joining block to create longer rails or varied stand configurations.
• Assembly: Essential for assembling stable, freestanding SYSTEM X speaker stands.
• Finish and Color: Typically supplied in black to match the SYSTEM X aesthetic.

This component facilitates custom configurations, allowing users to design speaker stands tailored to specific size and height requirements by linking multiple rails and support columns. Although specific dimensions or weight specifications aren't cited, it is consistent with modular joining plates used for maintaining structural integrity.

While no detailed descriptive marketing text or exhaustive technical data sheet is freely available online, the product is clearly positioned as a vital structural accessory within the B-Tech SYSTEM X series.
