Frequently Asked Questions
Are there any pre-cut gland holes?

No. The Wagobox-Capsule is an adaptable enclosure. This means that holes will need to be cut using an appropriate hole cutter to suit the gland that will be fitted. Gland holes are usually quoted as: M12, M16, M20, M25, M32, M40, M50 and M63.  These relate directly to the hole size required,  eg. M12 is 12mm diameter hole. 

What gland sizes can be used?

The Wagobox-Capsule can be used with either M12, M16 or M20 glands. However, the Wagobox-Capsule has in general been designed to be used with M20 glands.

What type of glands can be used?

Any type of gland can be used up to and including size M20.

How many glands can be fitted to the Wagobox-Capsule?

Up to 11.  3 glands can be fitted to the lid and 2 glands to each of the 4 flat sides of the base. Though this is a possible solution, care needs to be taken not to over do it!  Consider if each cable has three cores then there will need to 33 connection points within the capsule and this could then require multiple connectors to be joined together to make a common earth terminal for example. It may not be possible to get the lid back on!  As a rule of thumb we would recommend keeping to a maximum of 5 gland entries.

What connectors can be used with the Wagobox-Capsule

Any connector that is appropriate to the type of wire that needs to be connected.

OEM Options

We understand that some customers require enclosures for unique applications. That's why we offer bespoke modification of our existing Connexbox® products to meet your specific needs.


Our OEM projects include a European manufacturer of IoT environmental equipment who had created an ultrasonic level sensor for monitoring waste, sewage, and liquid levels. They approached us after seeing our IP68 Connexbox® Capsule and required a robust, waterproof enclosure to house the sensor.


After discussing their requirements, we began modifying the design of our standard IP68 Capsule and produced a prototype. Once approved by our customer, we manufactured the bespoke capsule to the required quantities and even laser engraved our customer's branding onto the product.

Contact our team today to discuss your specific requirements and let us create a custom solution for you.
