GAH-Alberts 412838 Gate Locking Device, 300 mm, Height-Adjustable

At 300 mm high, the GAH-Alberts 412838 is a gate locking device designed to be set into concrete. Its hot-galvanised steel construction is intended for ground installation.

Height adjustment gives 120 mm of movement, which can help position the locking point to suit the gate. A counterplate is included for bolting.

Would this suit a gate installation where the fitting needs to be embedded rather than simply attached to a surface? That distinction is central to choosing this device.

Key points

This is a ground-mounted fitting for concreting, not just a standalone bolt-on lock. The stated 300 mm height and 120 mm adjustment range are useful details to consider when planning its position relative to the gate. The device has a depth of 90 mm, while its backplate is 30 mm wide and 50 mm high, with a plate thickness of 3 mm. Three holes, each 5 mm in diameter, are specified for the backplate.

The counterplate provides a bolting point as part of the fitting. Together, these details make the product relevant for a gate project that already allows for concrete embedding and needs some adjustment in height. The listing does not describe the locking mechanism itself or specify which gate designs it suits, so those points should not be assumed from the product name alone.

How it fits

The device is intended to be mounted in the ground and concreted in place. That makes it a more suitable approach for an installation being planned around an embedded fitting than a simpler surface-mounted option. The stated adjustment of 120 mm gives some scope to align the locking position during fitting, it does not remove the need to plan around the gate and the intended concrete installation.

For a practical project, first establish where the gate needs to meet the locking point, then use the listed height and adjustment range to judge whether the fitting can be positioned appropriately. Its counterplate is for bolting, but the product details do not explain the fixings required or provide a fitting method. If you are replacing existing hardware, compare its mounting arrangement and measurements with this device rather than relying only on the general description of a gate lock.

Who it’s for

It makes sense if you are installing a gate with provision for a concrete-set ground fitting and want height adjustment as part of that setup. The stated dimensions and backplate details can also help when assessing whether the fitting is suitable for the space available. The hot-galvanised steel construction is a relevant detail for metal gate hardware, though the listing does not give a separate lifespan or corrosion-resistance rating.

It may not suit you if your project calls for a surface-mounted fitting rather than one set into concrete. A simpler bolt-on approach may be more appropriate where ground embedding is not part of the installation. Compatibility with a particular gate, post or existing lock is not specified, so the measurements and mounting arrangement matter more than the broad product category.

Buying verdict

The GAH-Alberts 412838 is worth considering when the installation calls for a concrete-embedded gate locking device and the 120 mm height adjustment is useful. Its listed size, backplate and hole details give practical points to compare against the planned fitting location. If you need a surface-mounted solution, or require confirmed compatibility with a particular gate, the available product information does not establish that this is the right match.
