Bulk Pricing & Trade-Exclusive Advantages

For B2B pros, volume unlocks real value: tiered discounts start at 10% off for 24 units, scaling to 25% for full cases of 100. No minimum order hassles—ideal for small trade runs or large-scale developments. Chrome plating offers fingerprint-resistant shine, reducing callbacks on visible installations, while the electro brass base layer boosts adhesion for 10+ year lifespans.

Wholesalers report 30% faster turnover on steel door chain stock versus competitors, thanks to universal mounting holes (52mm screw centers) fitting 99% of timber and steel doors. Integrate into your catalog alongside deadbolts and espagnolette bolts for complete door hardware bundles—boost average order value by 40%.​

Effortless Installation for Contractor Efficiency

Pre-drilled strike plates and self-tapping screws make fitting a 5-minute job, even for entry-level installers. B2B clients love the no-fuss design: surface-mount chain housing conceals fixings, maintaining clean aesthetics on rental properties. The 100mm length balances security with usability—preventing forced entry while enabling parcel drops and service calls.

Specify this steel door chain for social housing tenders or Airbnb conversions; its robust construction handles daily abuse from tenants or guests. Bulk packs arrive palletized, wrapped for forklift handling, slashing warehouse labor by 50%. Chrome finish resists yellowing under UV exposure, ensuring repeat business from satisfied specifiers.​
