Product Overview
The Chief KRA220B Extension Arm adds 6.5 inches of reach to Kontour K1 and K2 monitor arm mounts for conference rooms, training rooms, and commercial workstations that need extra range of motion. It is well suited to dual-arm mounts, pushing monitors back to free up work surface or reaching across deeper desks. This model ships in a black finish.
Product Description

The KRA220B Extension Arm accessory for Kontour K1 and K2 products provides an additional 6.5" (165 mm) of reach for installations requiring additional range of motion. It is a strong choice for dual-arm mounts, where it improves push-back of the monitors to free additional work surface real estate while also extending reach for deeper work surfaces. Adding the KRA220 reduces the total weight capacity of the mount it is used on by 15 lbs (6.8 kg); for example, adding a KRA220 to a K1D120 reduces the final configuration capacity from 25 lbs (11.3 kg) to 10 lbs (4.5 kg) per monitor. Plan the configuration around that adjusted capacity to keep the mount within its rated load. The black finish coordinates with other Kontour hardware for a consistent look. Need a lighter finish? See the silver KRA220S, or browse Kontour arms and accessories in the Chief collection.
