SENTINEL

SENTINEL is a brand associated with secure storage equipment for law enforcement, evidence handling, and controlled-access environments. The product line supplied by 3G Electric focuses on standard evidence storage lockers, a category of steel cabinet designed to hold physical evidence, personal effects, or controlled items in individual compartments. These lockers are built around a non-pass-through backing, meaning the compartments are accessible from one side only, which restricts removal from behind the unit. The primary closure mechanism across the range is a slam latch, allowing a compartment to be secured by pushing the door closed without a separate latching action. The lockers are finished in gray and ship fully assembled, reducing on-site installation steps. The available models differ primarily by compartment count, with configurations ranging from two compartments up to twelve compartments. This range allows a facility to match locker capacity to the volume of items expected in a given intake or temporary-hold area. The compartment count also affects the overall cabinet dimensions and the granularity of segregation, since each compartment provides a separate secured space. The non-pass-through design is relevant where the rear of the locker may be accessible from a different room or corridor, as it prevents someone on the opposite side from reaching into a compartment. The slam latch is a mechanical closure suited to high-frequency deposit and retrieval, where staff need to secure an item quickly and move on. Because the units ship assembled, they can be placed into service after positioning and, where required, anchoring. 3G Electric supplies the SENTINEL evidence storage locker line as part of its broader catalog of industrial and institutional equipment. For technical buyers, the relevant selection variables are compartment count, the non-pass-through backing, the slam latch closure, the gray powder-coat or painted finish, and the assembled shipping condition. The lockers are intended for controlled environments such as evidence rooms, property storage areas, intake and processing spaces, and other locations where chain-of-custody or controlled access is a consideration. 3G Electric supports the line by providing model-level specifications, part numbers, and availability information so that procurement and facility teams can specify the correct compartment count and confirm the physical configuration before ordering. The brand's evidence locker range is a focused product family rather than a broad catalog, which simplifies specification: the main decision is how many compartments are needed and whether the non-pass-through, slam-latch configuration matches the room layout and access pattern. 3G Electric can supply these SENTINEL lockers to customers worldwide, with the product data organized by SKU and manufacturer part number to support quoting and order processing.

Frequently asked questions

Common questions about SENTINEL from 3G Electric.

What is a SENTINEL evidence storage locker and how is it configured?

A SENTINEL evidence storage locker is a steel cabinet with multiple individually secured compartments, a non-pass-through backing, and a slam latch closure. The non-pass-through backing means the compartments open from one side only, so the rear of the unit does not provide access. The slam latch allows a compartment to be closed and secured by pushing the door shut. Units ship fully assembled in a gray finish. The main configuration variable across the line is compartment count, with models ranging from two to twelve compartments. This makes the locker suitable for evidence rooms, property storage, and other controlled-access areas where items need to be segregated and secured individually.

What compartment counts are available in the SENTINEL standard evidence storage locker range?

The SENTINEL standard evidence storage locker range supplied by 3G Electric includes models with 2, 4, 5, 6, 7, 8, 10, and 12 compartments. Each model uses the same basic configuration: a non-pass-through backing, a slam latch closure, a gray finish, and fully assembled shipping. The compartment count determines the number of separate secured spaces and affects the overall cabinet size. For example, the 2-compartment model (MPN 02AA-NPT) provides two large compartments, while the 12-compartment model (MPN 12AA-NPT) provides twelve smaller compartments. Selection depends on the expected item volume and the desired level of segregation.

What does non-pass-through backing mean on a SENTINEL evidence locker?

Non-pass-through backing on a SENTINEL evidence locker means the compartments are accessible only from the front of the unit. There is no opening or door on the rear panel, so a person standing behind the locker cannot reach into any compartment. This is relevant when the back of the locker faces a corridor, a different room, or any area with separate access. It prevents items from being removed from the rear and helps maintain control over the contents. The non-pass-through design is standard across the SENTINEL standard evidence storage locker models listed by 3G Electric, including the 2-compartment through 12-compartment versions.

How does the slam latch work on SENTINEL evidence storage lockers?

The slam latch on SENTINEL evidence storage lockers is a mechanical closure that secures a compartment when the door is pushed closed. It does not require a separate turning or latching action to engage. This is intended for situations where staff need to deposit or retrieve an item and secure the compartment quickly. Each compartment has its own slam latch, so compartments can be opened and closed independently. The latch is part of the standard configuration on all SENTINEL standard evidence storage locker models supplied by 3G Electric, including the 2, 4, 5, 6, 7, 8, 10, and 12-compartment versions.

Are SENTINEL evidence storage lockers shipped assembled?

Yes. SENTINEL standard evidence storage lockers ship fully assembled. This means the cabinet arrives as a complete unit with the compartments, slam latches, and non-pass-through backing already in place. On-site work is limited to positioning the locker and, where required by the facility, anchoring it. Shipping in assembled form reduces the installation steps compared with knock-down cabinets that require field assembly. The assembled condition applies across the SENTINEL standard evidence storage locker range supplied by 3G Electric, from the 2-compartment model to the 12-compartment model. Buyers should confirm doorway and corridor dimensions before ordering to ensure the assembled unit can be moved into the intended location.

What finish and color are SENTINEL standard evidence storage lockers supplied in?

SENTINEL standard evidence storage lockers are supplied in a gray finish. The gray color is consistent across the models listed by 3G Electric, including the 2, 4, 5, 6, 7, 8, 10, and 12-compartment versions. The finish is applied to the steel cabinet and compartment doors. Gray is a common choice for institutional and evidence-handling environments because it is neutral and does not show marks as readily as lighter colors. The finish is part of the standard specification and is not typically a variable across the range. Buyers should refer to the individual product data for any finish-related notes on a specific model.
