Manholes 50 mm: Specifying the Shallower Jawdah Manhole Item
Manholes 50 mm is one of two manhole items in Jawdah's drainage range; its material, sizes and the dimension that the 50 mm figure refers to are confirmed by Jawdah per project.
Manholes 50 mm is listed by Jawdah as a separate item from Manholes 70 mm. The name tells a buyer that the two items differ by a millimetre figure, but Jawdah's product data does not yet say what that figure measures or give a material, clear opening or load rating.
This page sets out what can be stated, what must be confirmed, and how to prepare an enquiry so the Jawdah team can match the 50 mm item to your floor build-up and access requirements.

Quick answer
Manholes 50 mm is a Jawdah manhole item named by a 50 mm figure. Jawdah has not published its material, opening size, load rating or what the 50 mm describes. Before ordering, ask Jawdah whether the figure is a recess depth, frame height or another dimension, and send floor sections, loads and quantities so the item can be confirmed for your project.
The Manholes 50 mm item
In the Jawdah inventory, Manholes 50 mm sits under the Manholes category together with Manholes 70 mm. Both are access items for drainage systems. The only published difference between them is the figure in their names.
Treat this item as a product that must be specified in conversation with the manufacturer: its identity is clear, but its technical sheet is not yet public.
Known and unknown data
Known: the item name Manholes 50 mm, its place in the Jawdah sanitary ware and drainage family, and the existence of a sister item, Manholes 70 mm.
Not published: material, clear opening, overall frame size, cover type, load rating, sealing, weight, finish and documents. Each of these is confirmed per project and is listed as required data.
What the 50 mm figure could describe, and why it matters
Manufacturers use millimetre figures in manhole names in different ways. Three readings are common in the market, and each changes what you check on your drawings. Confirm the correct one with Jawdah before selecting.
If the figure is a recess or tray depth, compare it with the total thickness of tile, adhesive or bedding that will fill the cover. If it is a frame height, compare it with the depth available in the screed above the chamber. If it describes another part, such as cover thickness, relate it to the load and lifting weight required.
- Recess (infill) depth: check against finish plus bedding thickness.
- Frame height: check against the screed depth above the chamber.
- Other dimension: check against load and handling needs.
Coordinating with the floor build-up
Whatever the figure describes, the cover top must finish flush with the surrounding floor. Prepare a section through the floor at each access point showing structural slab, screed, waterproofing, bedding and finish, with their thicknesses. The Jawdah team can then confirm whether the 50 mm item fits or whether the 70 mm item is the better match.
Where the access point sits in a wet area, show how the waterproofing membrane meets the frame.
Installation checks for this item
Set the frame on a full mortar bed so it is level and does not rock. If the cover is a recessed type, fill it with the same finish as the floor and keep the joint between cover and frame free of adhesive. Test that the cover can be lifted with its keys after the finish has cured.
Pitfalls when ordering Manholes 50 mm
These errors are easy to avoid with a short confirmation step.
- Assuming the 50 mm figure is a recess depth without confirmation.
- Ordering before the floor finish and its thickness are fixed.
- Leaving the traffic type out of the enquiry.
- Not stating whether a sealed cover is required indoors.
- Confusing this item with Manholes 70 mm on drawings or BOQ.
Manholes 50 mm compared with Manholes 70 mm
The two items share a category and differ by the figure in their names. If the figures describe the same dimension, the 50 mm item would be the shallower of the two and the Manholes 70 mm item the deeper. This remains to be confirmed by Jawdah.
For the general anatomy of manholes and cover types, see the Manholes category page.
