The plate vise itself is not a "real" vise in the sense that it lacks the jaws and any other moving parts.
Most "real" vises are not a suitable alternative to plate vises, as they require a sturdy workbench to operate. This severely limits their use in the field or on job sites.
The only genuine alternative to a sheet metal vise for use on the job site is the portable vise and workbench system known as the "portable workbench" and often marketed as the "job mate".
Portable desktops
Portable workbenches fold for easy transport and are equipped with non-slip feet, making them suitable for wet and slippery conditions.
The portable workbench includes a horizontally opening jaw with a maximum capacity of 205mm, which is just under double the size of the largest gripping hole on a sheet metal vise.
Also included are five adjustable "clamping pins" that the user can move to the desired position to hold a workpiece of almost any shape. This is an advantage over plate vises, which have holes to grip a predetermined shape and size and cannot be adjusted.
In addition, portable workbenches can be gripped both vertically and horizontally and can be set at a height of 595mm or 775mm meaning the user does not have to bend over, kneel or work at an awkward angle to the workpiece.
All in all, a portable workbench is a great alternative to a plate vise if you need a gripping tool that can accept a wider range of shapes and sizes.
However, if cost is a factor and the plate vise fits the size and shape of your workpiece and you feel like you can work from a less comfortable angle or position, the plate vise is much cheaper.
Sheet metal vises are also lighter and smaller than portable workbenches that need to be folded and unfolded each time they are transported. This makes it easier to transport the vise from place to place.
