🧩 Availability

🛒 Where to buy (UK)

Your best options are:

Pakprint Tapes Limited

• Official distributor
• Can supply genuine parts and confirm compatibility
• Industrial suppliers (e.g.Pakprint)
  • Usually quote-based
  • Useful if you need bulk or international shipping

⚠️ Important checks before ordering

Make sure:

• You have a K11 (2") head, not K12 (3")
• You want the complete guard assembly, not just the blade
• Your part number matches exactly (S460384593Z)

There’s also a “bumper blade guard” (S310097005Z)—that’s a different component, so don’t mix them up.

👍 Quick advice

If you’re repairing a worn head:

• Consider a full K11 service kit if multiple parts are worn (blade, springs, rollers)
• The blade guard often gets replaced alongside the blade for safety

If you want, tell me your machine model (or send a photo), and I’ll double-check compatibility or find the exact supplier with pricing in the UK.
