Werner Stabiliser Kit AC45
Best OverallPros
- Wide 1.2m spread prevents tipping
- Lightweight aluminium (2.5 kg)
- Rubber grips protect caravan sides
Cons
- May need adapters for very narrow rungs
- Price premium over basic models
The Werner AC45 is widely regarded as the gold standard for caravan ladder stabilisation. Its 1.2m spread creates a broad footprint that significantly reduces side-to-side wobble, which is critical when working on a caravan roof. Owner reviews consistently praise the secure fit on both extension and telescopic ladders.
The aluminium construction keeps the unit lightweight for easy transport, while the rubberised contact points prevent scratches on your caravan's paintwork. Some users note that the clamps are designed for rungs up to 45mm wide, so check your ladder's rung dimensions before purchase.
Draper Ladder Stay
Best BudgetPros
- Very affordable price point
- Simple clamp-on design
- Durable steel construction
Cons
- Heavier than aluminium models (3.8 kg)
- Narrower spread than premium options
The Draper Ladder Stay is a no-frills stabiliser that delivers solid performance for occasional caravan use. Its steel frame feels robust, and the clamping mechanism is straightforward to attach to most standard ladders. Many owners report that it eliminates wobble effectively on flat ground.
The main compromise is weight: at nearly 4 kg, it is noticeably heavier than aluminium alternatives. However, if you are on a tight budget and only need a stabiliser for a few trips a year, the Draper offers excellent value for money.
Sealey Ladder Stabiliser
Best Heavy-DutyPros
- Widest spread for maximum stability
- High 180 kg weight capacity
- Lightweight aluminium build
Cons
- Larger footprint may not suit tight spaces
- Higher price point
Sealey's offering is built for those who need extra reassurance on uneven ground. The 1.3m spread is the widest in this roundup, providing exceptional lateral stability that is ideal for tall ladders used on caravan roofs. The aluminium construction keeps the unit manageable at 2.8 kg.
Owner feedback highlights the robust clamping system that stays secure even on thicker rungs. The main trade-off is the size: the wider arms can be cumbersome to store in a caravan locker. It is best suited for owners with dedicated storage space.
Bahco Ladder Stabiliser
Best CompactPros
- Compact design for easy storage
- Lightweight at 2.1 kg
- Quick-release clamps
Cons
- Narrower spread reduces stability
- Not ideal for very tall ladders
Bahco's stabiliser is designed for caravan owners who prioritise portability. Its 0.9m spread is narrower than competitors, but the compact folded size means it can slip into tight storage compartments. The quick-release clamps make installation fast, which is handy for frequent setups.
Owner reviews note that it works well for single-storey caravan roofs but may feel less secure on taller ladders. It is best paired with a shorter extension or folding ladder. The aluminium build ensures it does not add significant weight to your kit.
Stanley Ladder Stabiliser
Best Versatile FitPros
- Adjustable clamps fit various rung sizes
- Good balance of spread and portability
- Rust-resistant coating
Cons
- Steel construction is heavier (3.5 kg)
- Clamps can loosen over time
Stanley's stabiliser stands out for its adjustable clamping system, which accommodates rungs from 30mm to 50mm wide. This makes it a versatile option if you own multiple ladders. The 1.1m spread offers a good compromise between stability and compactness.
Some owners report that the clamps may need periodic tightening after repeated use, but the overall build quality is solid. The steel frame is heavier than aluminium models, but the rust-resistant finish ensures longevity. It is a reliable mid-range option for caravan owners.
What to check before buying a caravan ladder stabiliser
First, measure your ladder's rung width and shape. Most stabilisers clamp onto round or D-shaped rungs, but some models have specific size limits. The spread width is also critical: a wider spread (1.2m or more) provides better stability on uneven ground, but may be harder to store. Weight capacity should exceed your body weight plus any tools you carry. Aluminium models are lighter and rust-resistant, while steel options are cheaper but heavier.
Mistakes to avoid when using a ladder stabiliser on a caravan
Do not assume a stabiliser makes the ladder completely immovable. Always place the ladder on firm, level ground and use a base plate if the surface is soft. Avoid over-tightening clamps, as this can damage ladder rungs. Never use a stabiliser with a damaged or bent ladder. Finally, ensure the stabiliser's contact pads do not scratch your caravan's paintwork; rubberised pads are safer than bare metal.
FAQs
Can I use a ladder stabiliser on any type of caravan ladder?
Most universal stabilisers fit extension, telescopic, and folding ladders, but you must check the rung width and shape. Some models require adapters for very narrow or wide rungs.
How wide should the stabiliser spread be for caravan use?
A spread of at least 1.0m is recommended for basic stability, but 1.2m or wider is better for taller ladders or uneven ground. Wider spreads reduce side-to-side wobble significantly.
Is a ladder stabiliser necessary for caravan roof work?
Yes, it is strongly recommended. Caravan roofs are often curved and slippery, and a stabiliser prevents the ladder from shifting sideways, which is a common cause of falls.
Can I leave the stabiliser attached to the ladder during storage?
Yes, most stabilisers can remain clamped to the ladder. However, check that the clamps do not cause pressure marks on the rungs over long periods, especially with aluminium ladders.
Do I need a stabiliser for a folding ladder used on a caravan?
Yes, folding ladders can still wobble on uneven ground. A stabiliser adds a wider base and prevents the ladder from tipping sideways when you reach out to clean the roof.
What is the weight limit for caravan ladder stabilisers?
Most models support between 120 kg and 180 kg. Always check the manufacturer's rating and ensure it exceeds your weight plus any equipment you carry.
Are aluminium stabilisers better than steel?
Aluminium is lighter and rust-resistant, making it preferable for mobile use. Steel is stronger and cheaper but heavier and prone to rust if the coating is damaged.
Can I use a stabiliser on a ladder with rubber feet?
Yes, but ensure the stabiliser clamps do not interfere with the rubber feet. Some models are designed to attach above the feet, leaving them free to grip the ground.
How do I install a ladder stabiliser on my caravan ladder?
Most models use a clamp-on mechanism: position the stabiliser on the desired rung, tighten the clamps evenly, and check for secure fit. Always follow the manufacturer's instructions.
Will a stabiliser fit my Werner or Little Giant ladder?
Yes, most universal stabilisers are compatible with these brands. However, check the rung dimensions and shape, as some ladders have non-standard profiles.
Can I use a stabiliser on a ladder placed on grass?
Yes, but the stabiliser's feet may sink into soft ground. Use a ladder base plate or plywood sheet to distribute the weight and prevent sinking.
Do I need a stabiliser for a short ladder under 2 metres?
It is still recommended, as even short ladders can tip sideways on uneven ground. A stabiliser adds an extra layer of safety for any ladder height.
Our verdict
For most caravan owners, the Werner Stabiliser Kit AC45 is the best overall choice due to its wide 1.2m spread, lightweight aluminium build, and universal fit. If you are on a budget, the Draper Ladder Stay provides reliable stability at a lower cost, though it is heavier. For heavy-duty use on large caravans, the Sealey Ladder Stabiliser offers the widest spread and highest weight capacity.
