The Spencer tapes with Release Nails are specialized logger’s tapes. They have a flexible Dymax 500mm extension which is designed to help protect the blade and endhook from kinking and breaking if rewound into the case too quickly. (Uncontrolled rewind can still damage your tape blade and could cause injury, so should be avoided). Metric on both sides.
The yellow coated measuring tape is made of special steel. It is particularly easy to read thanks to clear, double-sided marking. The centimeters and decimeters are indicated in black. The meter division is printed in red, other scale values in black.
