What the Locking Mechanism Does
A locking tape measure lets you hold a measurement without keeping constant tension on the blade. On the Excel Blades 25' Double Sided Locking Tape Measure, the lock is a sliding switch or lever on the housing. When engaged, it prevents the tape from retracting, so you can read the measurement or transfer it to a workpiece without the blade snapping back.
The lock is especially useful when measuring alone, as it frees one hand. It also helps when marking long distances on wood, steel, or fabric—you can lock the tape, align it, and mark without holding the end hook.
How to Use the Locking Tape Measure
These steps apply to the Excel Blades 25ft tape measure and similar double-sided locking models.
- 1. Extend the tape to your desired length: Pull the tape out from the housing. The stainless steel blade is sturdy enough for one-person use on most materials. For long distances, hook the end tab over the edge of the workpiece or have a helper hold it.
- 2. Engage the lock: Slide or press the locking mechanism until the tape stays in place. Confirm it is secure by gently tugging the blade—it should not retract. The lock holds the tape at the set length so you can read the measurement or mark the material.
- 3. Read the imperial markings: The tape has easy-to-read Imperial markings on both sides. Because it is double sided, you can read the measurement from above or below the tape, which is helpful when measuring in tight spaces or over your head. The markings are clear and spaced for quick reading.
- 4. Release the lock to retract: When finished, disengage the lock and let the tape retract slowly. The stainless steel blade returns smoothly into the housing. Avoid letting it snap back uncontrolled, as that can damage the end hook or the tape.

Materials You Can Measure
The Excel Blades 25ft tape measure works on wood, steel, plastic, fabric, plaster walls, PVC, paper, card-stock, stencils, film, photographs, tape, cork, vinyl, cloth, leather, cardboard, and foam boards. The durable stainless steel blade and sturdy end hook grip edges securely on most surfaces.
One trade-off: the tape is designed for Imperial measurements only. If you work primarily with metric units, you will need to convert or use a separate metric tape. Also, while the locking mechanism is reliable, it holds the blade at a fixed length—not a fine adjustment tool. For precise positioning, lock the tape then adjust the workpiece, not the blade.
