LockBlock - Mittelstopp für Fiat Ducato Schiebetür

LockBlock Door Stop for Fiat Ducato / Citroen Jumper / Renault Boxer

This is a door stop for the sliding door of a Fiat Ducato, functioning bidirectionally: it secures the door in a central position, preventing both accidental closure and complete opening. Should full opening be required, the rear magnetically held block can be easily removed and reattached later.

Two versions are available.

Version 1 is the initial version, my original design. It requires only one magnet. I submitted this version to the “Campfire der Ideen”, although unfortunately it did not reach the final round. Nevertheless, I wanted to make this component available to all interested van drivers. From the outset, I intended to offer it as a downloadable design. Furthermore, I sought a solution for those without 3D printers.

Therefore, I contacted Markus from SMaker3D. Markus refined the LockBlock in numerous details and included it in his shop. This is Version 2. In this version, the base is magnetically attached. For easier base removal, an optional loop can be added. The following video showcases the LockBlock:

A material kit with all necessary screws and magnets for Version 2 is also available.

Instructions for Both Versions:

With the door open, insert the base into the lower running rail. The oval recess indicates the correct position. The oval recess must be on the right. In Version 1, secure the base by tightening a 16-20mm long countersunk screw (3-3.5mm diameter).

Then, close the sliding door until it rests against the base. Subsequently, insert the rear stopper through the hole in the base. This might initially seem fiddly, but it becomes straightforward with practice.

You now have a fully functional central stop for your sliding door. This means the door stops and locks in the middle of the doorway. To close the door, pull the release handle as usual.

Advantages:

• The door is easier to close from the inside, as the handle is more accessible than with the door fully open.
• The hob remains wind-protected even with the door open.
• In winter, warm air escapes less readily.

Should full door opening be needed, the block can be removed with a single movement.

Required Materials:

Version 1:

• 18x3mm magnet with hole and countersunk screw
• 1x Countersunk screw approx. 16x3.5mm

Version 2:

• 1x Magnet for the base: 20x4mm
• 1x Magnet for the block: 10x5 - 3.4 mm bore for countersunk screw
• 1x Screw for the block: 3-3.5 x 40mm stainless steel full thread with countersunk head

Note: The design is intended for a 3.5mm screw. However, this may not fit all magnets due to significant manufacturing tolerances. In this case, a 3mm screw must be used, requiring securing with Loctite or a similar adhesive, or constructive narrowing of the hole.

The material kit for this version is available from the SMaker3D shop.

Printing Recommendations:

PETG has proven a suitable material. For adequate strength, I recommend 4 walls and 20% infill.
