Bar clamp Wolfcraft SZ 80-150 — clamp opening 15 cm, depth 80 mm, black/grey

The Wolfcraft SZ 80-150 bar clamp is a single-piece clamping tool designed for holding, gluing and assembling workpieces in woodworking and DIY tasks. It has a clamp opening of 150 mm and a throat depth of 80 mm, with a black and grey finish. The clamp provides adjustable clamping pressure along the bar to secure panels, frames and joints while adhesives cure or while performing assembly operations. The tool features an ergonomically formed handle with non-slip inserts and a galvanised spindle with trapezoidal thread for efficient power transfer.

Advantages

The clamp combines a rigid galvanised cavity-profile arm that resists bending across larger spans with a handle shaped for optimal hand force and non-slip grip. Its trapezoidal-thread spindle ensures consistent and efficient transmission of clamping force, while grooved edges on contact surfaces reduce the risk of slippage. A redesigned clamping arm allows the tool to be set flat on the upper part of the arm or on its back when rotated 90°, facilitating convenient placement during gluing and assembly operations.

Suitable for

• Holding workpieces during gluing of panels, frames and joints
• Clamping parts for woodworking and furniture assembly
• DIY repairs and small construction tasks requiring temporary fixation
• Securing pieces during adhesive curing or while performing precise alignment

Key specifications

• Clamp opening: 150 mm
• Throat depth: 80 mm
• Design: single-piece bar clamp with fixed bar and adjustable head
• Handle: ergonomically formed with non-slip inserts
• Spindle: galvanised with trapezoidal thread for power transfer
• Clamping arm: galvanised cavity-profile for increased rigidity
• Contact edges: grooved to reduce slipping
• Colour: black and grey

How to use

Position the bar clamp so the workpieces sit between the fixed head and the adjustable clamping head, then advance the spindle by turning the handle until the desired clamping pressure is reached. Ensure even contact along the surfaces to avoid localized pressure marks; use protective pads if working with delicate finishes. The clamp can be placed flat on its upper arm or rotated 90° to rest on its back for convenient positioning during glue curing or when freeing up workspace.

Usage recommendations

For best results when gluing, apply even pressure and allow adhesives to cure undisturbed. Avoid overtightening to prevent damage to workpiece edges; use protective pads when clamping finished surfaces. Keep the spindle clean and occasionally lubricate the thread for smooth operation and long service life.
