5400D, 5401D and 5423D Select Access Safes Comparison

Property managers, Airbnb hosts, NDIS care coordinators, and commercial contractors rely on select access safes from our key lock boxes range to store spare keys, access cards, and swipe fobs securely onsite without hiding keys under doormats or flowerpots:

1. 5401D & 5401EURD Wall-Mount 4-Dial Safe (83mm Body): Anchors permanently into solid face brick, poured concrete, or structural timber door jambs via four internal masonry screw holes. Features a resettable 4-wheel combination (10,000 user codes) and sliding shutter door to shield dials from rain and dust.

2. 5400D & 5400EURD Portable Shackle Safe: Designed for strata apartments, tenanted rental properties, and real estate inspections where exterior wall drilling is prohibited. Loops securely over spherical knobsets, lever handles, or metal fence rails with a 10mm vinyl-coated hardened steel shackle and protective closed-cell foam backing.

3. 5422D Shackle & 5423D Wall-Mount Push-Button Models: Replaces spinning rotary wheels with high-contrast telephone-style push buttons under a fitted weather cover, ideal for elderly residents, NDIS home-care support teams, and low-light entry points.

Reinforced Pin Tumbler and Laminated Steel Bodies

Original commercial padlocks engineered with laminated steel bodies stack individual zinc-plated steel plates riveted under extreme hydraulic pressure to absorb sledgehammer blows, cold chisels, and wedge attacks. Paired with hardened boron alloy or octagonal boron-carbide shackles (across the Magnum M1, M5, and Excell commercial series), dual ball-bearing locking levers, and precision 4-pin or 5-pin cylinders across our padlocks and accessories catalogue, these units secure factory gates, site toolboxes, shipping containers, and school lockers.

Outdoor Corrosion Protection With Weather Tough Covers

For farm gates, marine boat trailers, and coastal utility meter enclosures exposed to salt spray, mud, and red dust, models fitted with weather tough covers (including the 6121, 6125, and 312D outdoor series) encase the entire lock body, shackle seals, and keyway cylinder inside a high-impact thermoplastic shell. Combine these sealed outdoor units with the heavy-duty 730 (190mm) hardened steel bar from our hasp and staple locks category or our garage and gate locks range for complete outdoor perimeter protection across residential and industrial sites.

Industrial Hasps, Cable Locks and Safety Lockout Hardware

Beyond residential and commercial perimeter security, our range includes adjustable braided steel python cable locks (8413DPF and 8418D for trail cameras, bicycles, and ladder racks), resettable 4-dial brass combination locks (175D and 178D), heavy-duty steering wheel locks (252DAT), and industrial safety lockout hardware for workplace electrical and mechanical isolation under Australian WHS lockout-tagout procedures, including dielectric Zenex thermoplastic safety padlocks (410RED), multi-lockout scissor hasps (420 and 421), and universal miniature circuit breaker lockouts for industrial switchboards across Australia.
