Wedge Packers – Polypropylene – Precise Frame Alignment

Product Overview

Achieve precise, adjustable positioning of window and door frames with these heavy duty wedge packers. Each pair of tapered, interlocking wedges allows for fine tuning of level and plumb without removing fixings, offering an adjustment range of 9-14mm for accurate on-site alignment. The serrated faces lock securely to prevent slippage, while the rigid, non-compressible polymer ensures stable bearing and controlled lift with light taps. The material is non-absorbent and non-staining, ensuring clean, durable contact with frames and substrates.

These packers can be reused during set-out and left in place after final fixing. They are ideal for correcting uneven bases where flat packing is impractical, reducing the need for multiple shims while maintaining full bearing across the contact area. Optimized for both first-fix and finishing stages, these packers enable quick, precise adjustment to achieve a true and consistent datum.

Features & Benefits

• Opposing wedge action: Two wedges work together to raise or lower with small taps for precise control.
• Serrated, non-slip faces: Teeth interlock to resist creep during tightening and service.
• Rigid polymer construction: Maintains level and squareness under typical frame loads without crushing.
• Non-absorbent and non-staining: Suitable against common frame finishes and substrates indoors or out.
• Reusable during set-out: Insert, adjust, and lock; can be left in the final assembly.
• Reduced pack count: Replaces multiple flat shims where variable lift is required.
• Adjustment range: Used in pairs to level and fill variable gaps for accurate frame setting; 9–14mm.

Applications

• Window and door frame alignment: Establishing plumb, level, and square when bases are uneven.
• Threshold and sill correction: Taking up variation where flat shims would over-stack.
• Subframe and liner installation: Fine tuning reveals and clearances during fit-out.
• General joinery pack-off: Controlled lift for cabinets, fascias, and trims where incremental adjustment is needed.

Installation Guidance

• Prepare bearing surfaces: Ensure contact areas are sound and free from debris.
• Place in opposing pairs: Insert wedges teeth-to-teeth with serrations engaged and full-face contact.
• Adjust incrementally: Tap lightly to raise or slide back to lower until datum is achieved.
• Position at load paths: Locate near fix points and corners to support frame loads evenly.
