## Questions & Answers

**Q: What's de distance between the 2 holes to attach the base to the slides on 405 and 455 mm versions?**
A: For a 405mm drawer slide, the distance between the two holes connecting the base to the slide is 260mm. For a 455mm drawer slide, the distance between the two holes on the base to the slide is 310mm.

**Q: Do they lock out when extended?**
A: Thank you for your inquiry, this keyboard slide in the innermost position of the slide in the cushion pad can be locked to prevent the keyboard tray from slipping out without force.

**Q: Will this fit a keyboard of size 50 cm x 30cm?**
A: They are runners so you need to add a base for the keyboard to sit on which can be any size you want it to be within reason

**Q: what is the distance between the support brackets (internal, external) and what is the width of the bracket where it attaches to desk? Many thanks.**
A: The overall width of the bracket is 50mm. The width of the bracket that attaches to the desk is 25mm and the width of the bracket that attaches to the underside of the keyboard tray is 15mm. BTW excellent brackets. Better than anything from the usual DIY stores. Only thing it takes about a week or so to arrive as from china but dont let that put you off. Very solid.

    Works wonderfully
  

*by J***E on Reviewed in the United Kingdom on 22 February 2024*

Much better than the ones my desk came with originally, these feel sturdier and work perfectly. Would recommend if your old ones give out frequently. Have been using these for a little under a year.

Good sturdy construction and does the job well,i have installed a 61key musical keyboard under my desk,only improvement i would have liked would be to have had slightly longer or thicker support brackets to prevent side ways movement.never the less good enough!
