Water tank retaining frame
This galvanised zinc steel frame is made with CE standard struts that have been tested to construction industry standards for load bearing.
The frame has pre-drilled holes in the base to accommodate a huge variety of anchor bolt positions on your van floor.
Should you wish too, you will easily be able to attach all of the purifying system without drilling through the frame. Separate spring nuts are supplied to allow the user to do this.
Once installed, the tank can still easily be removed if needed by unbolting the support straps.
We are aware that a large majority of the window cleaning trade operate their vehicle on a daily basis with nothing other then a ratchet strap holding 250l (1/4 tonne) of water. The Cleaning Warehouse is offering a cost conscious way of avoiding this lethal trap.
This kit comes in 3 easy to put together pieces for either your mechanic to install or any competent person.
Please note that this kit is for the frame only and no bolts come with this kit so please pop down to your local hardware shop. Our recommendation is a minimum of 6 bolts for secure fitting.

350 L Flat Tank Retaining Frame — FAQs
1. What is this product?
It’s a retaining frame designed to hold a 350 litre flat water tank securely in place — especially in vans, trailers or workshops.
2. What does the frame do?
The frame stops the tank from moving, shifting or tipping during transport or everyday use, protecting both the tank and your vehicle.
3. What material is it made from?
It’s made from galvanised zinc steel with CE‑standard struts — strong and corrosion‑resistant, suitable for professional trade use.
4. Does the tank come with the frame?
No — the water tank is not included. This product is the frame only, and you must purchase a compatible flat tank separately.
5. Is it easy to install?
Yes — the frame comes semi‑assembled with a full set of instructions and splits into three pieces that are straightforward to put together for a mechanic or competent DIYer.
6. How is it fixed to the floor?
The base has pre‑drilled holes to fit anchor bolts for securing the frame to your vehicle floor — giving flexibility in bolt positions. Separate anchor bolts are not included.
7. Can I attach other equipment to the frame?
Yes — spring nuts are supplied, so you can mount your water purification gear (e.g., pumps, filters) without having to drill through the steel frame.
8. Can the tank be removed after installation?
Yes — once installed, you can still remove the flat tank easily by unbolting the support straps if needed.
9. What is it ideal for?
This frame is ideal for window cleaners, valeters and other tradespeople who transport water storage tanks and want a more secure setup than just using straps.
10. Why choose a frame over straps?
Many operators secure tanks with ratchet straps alone, but a dedicated frame improves safety and stability, reducing wear and tear on tanks and vehicle interiors — a more professional solution.
