Not everybody will need a ladder stopper. Most people will use an A Frame stepladder which has it's own stay, but for those using an upright lean to ladder for tall / outdoor work, a ladder stopper is a great way of securing your ladder without needing someone to hold it in place for safety.
We decided to invest in the Zarges Ladder Stopper because my husband has a very tall ladder which he uses on the house to access the roof - he uses it to clean out the gutters which get blocked by the leaves from the tall oak tree next to our house, to clean the windows, to make any adjustments to our aerial or freesat dish, and to make small repairs to the roof itself. I used to get the job of holding the ladder but now we have a little girl it's easier to have him do any work when I'm away looking after her. Hence the Zarges Ladder Stopper. We bought ours from an independent DIY shop locally, and it was £49.99 in the sale for an 18 inch version which is wider than our standard width ladder. This might sound a bit pricey but since when do you trust your ladder safety to a cheaper alternative ;) also, we saw it as a worthwhile investment in an area where a window cleaner charges £15 a time!
So, the Zarges Ladder Stopper. It's made of heavy duty ridged aluminium with a black rubber grip around the side which faces the ground. The ladder stopper can be used on any sort of ground other than loose gravel and very wet mud, both of which are far too dangerous to use a ladder on in any case. You could get away with the mud if you put down a supporting large piece of wood, possibly.
The ladder feet sit in front of the stopper and stop it from pushing out and therefore falling away from the upper surface it's leaning against. This is especially good for snug places where you need a fairly steep ladder at a narrow angle.
My husband advises me it gives a good footing to the ladder and he feels safe when he's using it, which is reassuring (especially given the price!). It's well made, has never rusted and feels like a quality item which is also good to know.
Overall, I understand that a ladder stopper isn't for everyone but to any keen DIYer (or window cleaner, aerial repairman etc) it's a really key piece of safety equipment and I personally wouldn't be without it. I've never tried another brand of ladder stopper, but the Zarges Ladder Stopper is well worth the money and I highly recommend it if there is something you need. I have seen the Zarges brand in B&Q so it's worth a look in there for it, too.
Overall - 5 stars out of 5, the Zarges Ladder Stopper is a good buy.
