NRH 5101-96K Toggle Latch with Lock Hole | Heavy Duty Lockable Draw Catch

NRH 5101-96K Toggle Latch - SPCC Steel, Brushed Finish, Security Lock Hole, 150kg Load

The NRH 5101-96K is a professional‑grade toggle latch engineered for applications requiring both secure closure and the option for added physical security. As confirmed by the official specification image, it is constructed from SPCC steel with a durable brushed finish - a satin, non‑reflective surface that resists fingerprints and minor scratches. The latch includes a critical security feature: a dedicated Φ2.4mm lock hole on the hook mechanism, allowing easy addition of a padlock, security seal, or wire tie to prevent unauthorized access. With a net weight of 88g and an outstanding 1475N (150kg) tensile load, it delivers exceptional holding power for heavy doors, lids, or vibration‑prone enclosures. Clear “NRH” branding ensures traceability and quality assurance.

As a product of NRH Box Hardware (established since 1996), this latch is manufactured under a certified quality management system. Regarding international compliance (ISO 9001:2000, SGS, REACH, RoHS, SVHC), these standards can be supported based on customer requirements and applicable costs - please contact us for specific certification needs. OEM and ODM services are available for custom hole patterns, lever shapes, logo engraving, or surface finishes. Detailed 2D engineering drawings and 3D CAD models are provided upon request to streamline your product integration.

Key dimensions: overall length 119.5mm, width 39mm, mounting holes 4×Φ4.5mm, lock hole diameter Φ2.4mm. Refer to the engineering drawing for complete dimension details.

Why a Brushed Finish on SPCC Steel?

SPCC steel (cold‑rolled carbon steel) provides excellent formability and strength at a cost‑effective price point. The brushed finish is achieved by mechanically abrading the surface with fine abrasive belts, creating a uniform, linear satin texture. Benefits include:

• Conceals minor scratches and wear - the directional pattern hides daily handling marks better than a mirror or chrome finish.
• Reduces glare - ideal for operator panels, outdoor cabinets, or any application where light reflection is undesirable.
• Provides a premium industrial aesthetic - matches the look of brushed stainless steel equipment.
• Good corrosion resistance - when combined with a clear protective coating (optional), it offers adequate protection for indoor or sheltered outdoor use.

For applications requiring full corrosion protection, consider our SUS304 stainless steel variants with vibratory or electropolished finishes.

Primary Applications - Engineered for Security and Strength

This latch is engineered for securing enclosures where tamper‑evidence or restricted access is important:

• Secure storage and transport cases: Lockable tool chests, sample transport cases requiring tamper‑evident seals, field service kits, and calibrated equipment boxes
• Industrial control and utility cabinets: Electrical panels, PLC cabinets, network server racks, and outdoor communication boxes where a padlock may be added
• Logistics and shipping containers: Equipment cases for sensitive goods, reusable shipping containers needing a seal point
• OEM machinery and equipment: Integration into machinery guards, access panels, or inspection hatches that require occasional lockdown
• Public infrastructure and kiosks: Payment terminals, EV charging station enclosures, and vending machines requiring padlockable service doors

How It Works - Over‑Center Toggle with Integrated Security Lock Hole

This latch functions as a standard over‑center toggle mechanism for robust daily closure. Pushing the lever down engages the linkage, pulling the hook tight against a strike plate and locking the two panels together with a positive mechanical stop. The over‑center geometry ensures the latch cannot open under vibration or accidental impact without deliberate lever lift.

Its standout security feature is the Φ2.4mm lock hole integrated into the hook. When the latch is engaged, this hole aligns with a corresponding point on the base or strike plate (see engineering drawing), allowing a padlock shackle, security wire, or numbered seal to be passed through. This physically prevents the latch from being disengaged without first removing the external lock or seal - providing tamper‑evidence and theft deterrence.

Features & Technical Benefits

• Integrated security lock hole (Φ2.4mm): Accepts standard padlocks, security ties, or wire seals - upgrade from “closed” to “locked”
• Extremely high load capacity: 1475N (150kg) tensile load - suitable for heavy industrial doors, large flight cases, and machinery guards
• Durable SPCC with brushed finish: Combines strength with a premium, low‑glare surface that resists fingerprints and minor abrasion
• Spring‑assisted over‑center action: Smooth one‑handed operation; positive tactile feedback upon full closure; resists vibration loosening
• Precision mounting: 4×Φ4.5mm mounting holes on a robust base plate; 1.4mm material thickness (typical) for secure attachment
• Clear branding and traceability: NRH logo stamped on product, backed by ISO 9001 quality system
• OEM/ODM flexibility: Custom lock hole diameters, lever lengths, finish options (e.g., powder coating), or logo engraving available
