Vortex Adjustable Jubilee Clamp 1" to 15"

VORTEX ADJUSTABLE JUBILEE CLAMP – One Clamp for 1"–15"

The Vortex Adjustable Jubilee Clamp is the simple, reliable way to secure grow-room ducting without guessing sizes.

Built from corrosion-resistant stainless steel, it tightens smoothly to create an airtight seal on fans, filters, silencers, and tent ports.

One clamp covers a huge range of diameters – ideal for installs, upgrades, and quick fixes.

• One size, many jobs; fully adjustable from 1" to 15" (≈ 25–380 mm)
• Stainless steel build; rust-resistant, durable, and long-lasting in humid grow rooms
• Airtight connection; heavy-duty screw drive for precise, even clamping pressure
• Universal fit; works with all common ducting, fans, carbon filters, and silencers
• Reusable; loosen, reposition, and re-fit during maintenance with no waste

Why Choose an Adjustable Clamp

Different fans and filters often mean different collar sizes. Instead of keeping a drawer full of fixed clamps, this adjustable Jubilee clamp covers them all. It’s perfect for growers who change layouts, switch fan sizes, or want a dependable spare that always fits.

Built for Grow-Room Conditions

Grow spaces are warm and humid, so hardware needs to last. The Vortex clamp uses stainless steel for the band and housing, resisting corrosion and maintaining tension over time. The worm-drive mechanism applies even pressure around the collar to help prevent air leaks and keep negative pressure stable.

Compatibility

Use on flexible aluminium or combi ducting, hard collars on inline fans, carbon filters, silencers, and tent ports. The wide adjustment range makes it suitable for common sizes (4", 5", 6", 8", 10", 12", 14" and more).

How to Use

1. Position: Slide the clamp over your ducting before seating the duct on the fan/filter collar.
2. Seat: Push the duct fully onto the collar for maximum grip and seal.
3. Tighten: Turn the screw with a flat-head screwdriver or nut driver until snug and uniform.
4. Check: Run your system and feel for leaks; tighten slightly if needed.

Top Tip: For the best seal, ensure the clamp sits on the rigid collar (not over wire ribs), and double-clamp on high-pressure runs or long duct lengths to minimise leaks.
