Bernstein 7-503 Folding Rule - Plastic - 1m

The rule is primarily made of plastic, with steel spring joints for its folding mechanism.

The rule extends to a maximum length of 1 meter.

This rule features metric measurements, specifically in centimeters (cm) and millimeters (mm).

The anti-abrasive coating is an integrated part of the material and is not designed to be replaced. Its purpose is to extend the life of the markings.

While accurate for general use, the plastic construction may not be as durable or rigid as metal folding rules typically preferred for heavy-duty professional carpentry where extreme precision and longevity under harsh conditions are critical.

Store the rule folded in a dry environment, away from direct sunlight and extreme temperatures. Avoid kinking or bending it beyond its intended folding motion.

The folding rule weighs approximately 60 grams.

Gently flex the joints or wipe them with a dry cloth. If stiffness persists, a tiny amount of graphite powder (pencil lead) can be applied to the joint mechanism. Avoid oil-based lubricants, as they can attract dust.

Ensure the rule is clean. The anti-abrasive coating should protect the markings under normal use. If markings are worn, it may indicate excessive abrasion or prolonged exposure to rough surfaces.

Check that the joints are fully engaged and that no debris is obstructing their movement. If the spring mechanism is weakened due to excessive wear, the joint may not hold as firmly.
