What Are C. S. Osborne No.250 Stretching Pliers Used For?

Stretching Upholstery Leather

Leather upholstery often requires careful tensioning to achieve a smooth, properly fitted finish.

These stretching pliers grip the material securely, allowing the upholsterer to pull it into position before fastening it to the furniture frame.

The hammer-style jaw provides additional leverage when working with heavier leather or materials requiring a stronger pull.

Take care to grip leather within concealed fixing allowances wherever possible, as excessive pressure may leave marks on finished surfaces.

Stretching Canvas and Heavy Upholstery Fabrics

Canvas and other upholstery materials can be difficult to tension evenly by hand.

The No.250 pliers provide additional gripping strength and leverage, helping the upholsterer position the material while maintaining tension.

They are particularly useful when working around timber furniture frames where the covering must be drawn tightly into position before fixing.

Fitting and Replacing Upholstery Webbing

These pliers can also assist when stretching suitable upholstery webbing across furniture frames.

When replacing damaged or deteriorated supporting straps, controlled tension is essential to achieving the intended support and comfort.

The tool can be used when working with compatible rubber and woven upholstery webbing, including materials such as Atlas Reinforced Rubber Webbing and Genuine Pirelli Black Rubber Webbing, subject to the material and fitting requirements.

How Does the Hammer-Style Jaw Work?

The distinctive hammer jaw is the principal feature of the C. S. Osborne No.250.

Unlike ordinary gripping pliers, this design allows the upholsterer to use a suitable furniture-frame edge as a levering point.

Once the material has been gripped between the jaws, the hammer section is positioned against the frame. Moving the handles creates leverage, increasing the pulling force applied to the material.

This makes it easier to tension demanding upholstery materials without relying entirely on hand strength.

The furniture frame must be sound, and polished or delicate surfaces should be protected before applying leverage.

Using the No.250 Stretching Pliers

1. Inspect the furniture frame and identify a suitable levering point.
2. Position the leather, canvas or webbing ready for tensioning.
3. Grip the material securely within the plier jaws.
4. Rest the hammer jaw against a suitable, protected frame edge.
5. Apply steady leverage until the required tension is achieved.
6. Secure the material using the appropriate upholstery fixing method.

Avoid overstretching the material or applying excessive pressure to fragile timber frames.
