How to Replace a Caravan Window Latch: A Simple DIY Guide

A well-working caravan window latch is essential for ventilation, security, and trouble-free touring. But like any moving component, window catches are prone to wear over time – especially the spring-loaded types commonly found on modern caravan windows found in vans from Supreme, Leader, and many others.

The good news? Replacing a faulty caravan window latch is a quick five-minute job you can easily tackle yourself. Below is a practical step-by-step guide inspired by our Adelaide RV workshop team to help you restore your window to perfect working order.

Why Caravan Window Latches Fail

Most caravan windows use a latch that relies on a small spring and ball bearing to lock into position. When these parts wear out or break, you’ll notice:

• No tension on the latch

• The catch flops loosely

• The window won’t stay securely shut or doesn’t hold its open position

If you feel that lack of resistance, the caravan window latch is likely due for replacement.

Before You Start: What You’ll Need

Fortunately, you don’t need specialist tools or mechanical experience. Most latches are:

• Held on by two small screws

• Backed by a piece of double-sided tape

• Mounted between the inner and outer window panels

This means you can remove the latch from the inside without accessing the back of the screws.

Replacement latches are widely available from major RV parts stores or online. Though keep in mind that windows will have standard latches, and then left and right-handed latches for the gas-struts, so double-check you’re ordering the type.

Step-by-Step: How to Replace a Caravan Window Latch

1. Identify the Faulty Part

Open and close the window while checking for tension. If the latch feels loose or doesn’t lock into position, the spring mechanism is worn.

2. Remove the Old Latch

Most latches come off easily:

1. Undo the two screws holding the latch in place.

2. Give the latch a gentle wiggle – this helps break the bond of the double-sided tape used during installation.

3. Lift the faulty latch away from the window.

Even though the screws anchor into material between the window layers, they will release cleanly from the inside.

3. Assess Whether the Strut Needs Replacing

Some windows feature a linkage between the latch and the support struts that hold the window open. If only the catch is damaged, it simply unclips.

If the strut itself is worn or cracked, you’ll notice reduced support when opening the window. In this case, remove the additional screw securing the strut to the window frame and replace the whole assembly.

4. Fit the New Latch

Align the replacement caravan window latch in the same position as the original:

• Press it lightly against the frame so the double-sided tape sticks

• Reinsert and tighten the screws

• Test the latch to ensure it locks firmly into place

The principles are the same across most caravan brands, even if the latch shape varies slightly.

Pro Tips From the Adelaide RV Team

• Carry a spare latch in your caravan toolkit – they take up no space and can save you hassle on the road.

• Replace left and right pairs together if they’re looking worn; it helps maintain even tension.

• Don’t force a sticky latch – this often causes the spring to fail prematurely.

• Test your windows regularly as part of your pre-trip check.
