1m (3ft) Steel Tape Measure with Keychain, Metric and Imperial Blade, Compact Size

This is a compact tape measure with a 1 metre blade marked in metric and imperial. A keychain fitting lets you carry it in a pocket or on a bunch of keys.

It suits quick checks when you plan a camera position, a bracket spot or a short cable run. The blade is 1m, or 3ft, so it is not made for long cable measurements.

For a longer run, measure in stages or use a longer tape. It is made of stainless steel and suits measuring during installation and survey work.
