Rugged Phone Dimensions: What a Mount Drawing Needs

When fitting a rugged phone into a mount, request the relevant mechanical drawing instead of designing from length, width and thickness alone. Overall dimensions describe the body envelope; they do not locate buttons, camera windows, connectors or retaining surfaces.

Start with the published size, then request the interface

The current R4-T listing gives 121 × 59.2 × 18.3 mm and 190 g. Those facts can help shortlist a compact device. They are not a manufacturing drawing, tolerance specification or proof that an existing holder fits.

Define the configuration being measured

State whether the phone is bare or fitted with a case. Identify the cable and any closure position required during use. Ask the responsible engineering team which drawing revision represents the supplied device and whether a later hardware change affects fit.

Do not invent a dimensional tolerance from the number of decimal places in a brochure. If the clearance matters, request an explicit value or agree a sample-fitting process.

Review a sample before releasing the mount

With the approved phone configuration, check insertion, retention, removal and the normal operating task. Record interference and any force needed. If a part must be forced or a cover cannot sit correctly, resolve the design rather than accepting it as a workaround.

A fit trial is not an impact or ingress test. For the complete accessory review, use the phone carrying-setup guide.

What should you send to Phonemax?

Provide the model, intended mount, connection needs and drawings. Confirm which mechanical information can be supplied and what sample review is appropriate. No custom mounting interface, retention strength or protection result is promised here.
