Cacti anti-climb spikes

These strips of plastic spikes fix to anything you don't want people or stray cats to climb on or over. They won't stop a determined burglar (what will?) but they WILL deter the opportunistic intruder. Each strip is 45cm long, and consists of loads of spikes in 3 rows.If fixing to a very narrow surface(2 cms or less) the strips can be cut down into single-rows.

I've tried several makes, and the Cactus afe definitely the sharpest- won't lacarate or leave flesh hanging in shreds, but will cause severe discomfort bordering on pain and will draw blood. Quite discrete when fitted, and legal. Highly recommended. If screwing or nailing proves difficult, can be stuck quite successfully using Pink Grip (about the only adhesive which will adhere to polypropylene)
