[QUOTE="roys, post: 498385, member: 5044"] I would try and keep the main body of your backbox intact and enlarge one of the 20mm knockout holes to 25mm either by using something like a cone drill (Screwfix 5911V for example) or a half round file. Put a 25mm grommet over the hdmi plug on the cable first then put the plug end through the new 25mm hole then fit the grommet on. Or if you are using the oval conduit and it fits through the hole stick it into the backbox by about 10mm, then no need for the grommet. [/QUOTE]
