Multiquip VHKIT20FT 20 Foot Extension

The Multiquip VHKIT20FT 20 Foot Extension is a genuine OEM component designed for FX40G6 high cycle concrete vibrators. As a direct OEM replacement sourced through Multiquip's authorized parts program, VHKIT20FT is built to the same specifications as the original equipment — ensuring a correct, hassle-free installation. Note: This extension is also referenced for use with FX50G6 models; consult the Bill of Distribution Table (BDT) to confirm exact fitment for your unit before ordering.

Key Features

• Genuine OEM Construction — Manufactured to the same material and dimensional standards as the original Multiquip flex-shaft extension, preserving vibration transfer efficiency across the full shaft length.
• Direct Swap Installation — Connects to FX-series frequency vibrator heads and backpack power units using the same coupling interface as the factory shaft, requiring no adaptation.
• Compatible with FX40G6 High Cycle Vibrators — Confirmed for FX40G6 equipment; cross-reference the BDT for FX50G6 applicability before ordering.
• Full 20-Foot Reach — Extends the operator's working depth and reach, allowing consolidation of deep concrete pours without repositioning the power unit.
• Maintains Vibration Integrity — A worn or damaged extension causes energy loss along the shaft, resulting in inconsistent consolidation. Replacing it with a correct OEM unit restores full vibration output at the head.

A flex-shaft extension on a concrete vibrator transmits rotational energy from the backpack power unit down to the vibrating head submerged in fresh concrete. The extension must flex freely while maintaining a tight, balanced drive connection — any kinking, fraying, or coupling wear along its length reduces the vibration frequency reaching the head, which leads to under-consolidated concrete with air pockets and voids. Replacing a damaged or worn extension with the correct Multiquip VHKIT20FT restores consistent energy transfer and keeps the vibrator performing as intended on the pour.
