Flat pack computer desk - drawer slider issue.

[Jules78]

Hi I have just had a large computer desk flat pack built by my handyman however the keyboard drawer will not slide in all the way and sticks halfway out

the drawer sliders were already installed when delivered every other drawer is fine can you give me some idea why and should I perhaps replace them?

@Jules78, 

I'm not too sure about that, it appears to be installed the correct way. Here's a video on How to install drawer runners. There are obviously not exactly the same as yours but it might assist you in knowing where the two halves need to be mounted.
