How delivery works
We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.
Delivery areas
Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.
If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.
What to expect on delivery day
- Deliveries are typically kerbside.
- Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
- Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.
Why delivery can cost more than typical parcel delivery
Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.
Returns
Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.

Product Overview
Brown U Packers for the precise positioning of window and door frames. They can be easily slid around existing fixings without removing screws, helping to maintain accurate datum and line during set-out.
Each packer is colour-coded for quick on-site identification. The rigid, non-compressible polymer provides a stable bearing under typical frame loads, while the internal comb design ensures a secure grip that resists movement during tightening and final fixing.
The material is non-absorbent and non-staining, ensuring a clean, professional installation against both frames and substrates. These U shaped shims reduce stack counts while maintaining plane and plumb.
Used singly for confident pack-off or combined with finer sizes to tune level and reveal, they maintain consistent plane across the bearing face to protect frame profiles and finishes.
The 5mm thickness is ideal for wide gaps and firmer fixing where a substantial correction is needed.
Features & Benefits
- Colour coding: Brown body provides quick visual confirmation of size in mixed sets and on busy sites.
- U-shaped profile: Slides around screws and anchors without removal to speed placement and adjustment.
- Internal comb: Interlocks with substrate or fastener line to resist slip and creep during tightening.
- Non-compressible polymer: Maintains level and square under typical frame and trim loads without crushing.
- Moisture and rot resistance: Non-absorbent material suitable for interior and exterior use.
- Clean edges and flat faces: Distributes bearing evenly to protect frame finishes and substrates.
- Reusable during set-out: Can be repositioned during dry-fit and left in place for final fix.
- Thickness: Ideal for wide gaps and firm fixing with reduced stack complexity; 5mm.
Applications
- Window and door frame setting: Packing substantial base variations while holding square.
- Batten and furring alignment: Establishing datum over irregular substrates with fewer shims.
- Hardware seating: Backing heavier brackets, rails, or plates needing solid bearing.
- Thresholds and ramps: Creating consistent bearing where levels vary significantly.
- Façade and cladding prep: Levelling battens where deeper offsets are present.
Installation Guidance
- Assess substrate: Ensure bearing areas are sound, clean, and free from debris before packing.
- Dry fit and level: Position packers at known load points to establish line, level, and plumb.
- Slide around fixings: Use the U-slot to place packers without removing screws or anchors.
- Stack with control: Combine sizes only as required, keeping full face-to-face contact.
- Fix and check: Tighten gradually and re-check plumb/level after each adjustment.
- Trim and leave in place: Do not remove after fixing; packers form part of the final assembly.
Compliance & Performance
- Material: Rigid, non-compressible, non-absorbent polymer suitable for frame setting and packing.
- Durability: Resistant to moisture, rot, and common site contaminants; non-staining against most frames.
- Temperature stability: Remains reliable across typical site temperature ranges during installation.
- Use limitation: Intended for setting and packing; not a structural load-bearing shim.
- Important note: Always maintain full bearing and verify the load path; wear appropriate PPE during installation.
