FAQ

Technical Support – Frequently Asked Questions

How do I identify the right spare part?

Every RAX door ships with a serial number plate and an exploded-view technical drawing. Send us the serial number and we identify the exact part needed – no guesswork, no wrong orders.

What if my door is out of warranty?

Parts are supplied at factory cost plus shipping. No markup. Your tooling is still archived for up to 5 years, so even custom parts are manufactured without new setup fees.

Can you upgrade my existing door?

Yes. Send photos and your model number. We engineer retrofit kits – new motors, control boxes, safety devices – that bolt onto your existing frame. See our door operators range for compatible upgrades.

Do you stock spare parts or make to order?

Standard wear parts (rollers, springs, cables, photo-eyes, fuses) are stocked for immediate dispatch. Custom panels and specialty parts require 7-12 days production from archived tooling.

What is excluded from warranty?

Damage from improper installation, modification without RAX approval, natural disasters, and normal wear beyond rated cycles are excluded. When in doubt, contact your account manager – we resolve grey areas in your favour.
