90° Angle Tensioners — ABS Plastic, 50 x 80 mm, 4 clamps Why you need these angle tensioners Achieve fast, precise 90° alignment for stronger joins and cleaner results. Ideal when accuracy matters for furniture, frames, or finished surfaces. Hold parts securely while glue sets or when doing tack welding, eliminating the need for complex jigs or constant manual support. Durable ABS construction resists oxidation and wear, so the tensioner keeps performing through repeated use. Key benefits and problem solving Precise positioning: The 50 x 80 mm 90° angle ensures consistent, square corners for reliable assembly and repeatable results. Secure fixation: Four integrated clamps provide stable pressure on workpieces to prevent slipping during gluing or welding. Surface protection: Smooth, rounded edges reduce the risk of marring or denting delicate wood, tile, or stone surfaces. Long service life: High-strength ABS material offers good mechanical durability and oxidation resistance for extensive DIY or trade use. Versatile compatibility: Works with wood, stone and ceramic tile, so you can use the same tool across multiple projects and materials. How it stands out Compact, ready-to-use angle with four clamps built in — no extra clamping setup required. Simple operation makes it suitable for hobbyists and professionals who need fast, repeatable squaring of parts. Typical use scenarios Assembling furniture: Hold two cabinet panels at a perfect 90° while you apply adhesive and fix with screws for accurate, square cabinets. Picture frames and small woodworking: Secure frame corners during glue-up to maintain consistent miter alignment and clean joins. Tile and stone installations: Clamp corner pieces of decorative insets or small stone elements while adhesive cures to keep edges flush and square.
