If you are intending to purchase and install the Gliderol steel roller door then you need to start by making sure you order and specify the right size roller door. The Gliderol roller door can only be installed to the inside face of a structural opening or behind a suitable fixing structure such as a timber framework.

Width Dimensions Explained
The Overall Width is also the reference for the Ordering Width when specifying and ordering a Gliderol roller door and is the garage Structural Opening Width plus the curtain overlap on each side which is 25mm each on a roller door up to 3400mm total width or 50mm each side on a door over 3348mm. The room required for installing the door is different again as there are large supporting steel brackets at higher level which are fitted wider than the roller guides referred to in the ordering width.
Example: A 2500mm wide garage opening requires a further 50mm adding for the 2 no. 25mm guides each side giving an Ordering Width size of 2550mm.
Summary of ordering width requirements
‘A’ Series door width
Opening width + 50mm (2”) minimum
‘AA’ Series door width
Opening width + 100mm (4”) minimum
Windlock ('AA' doors only)
Opening width + 140mm (2 3/4”) minimum
Important:
The support brackets and fixing lugs on the guides make the total width required on a basic manual door 90mm wider EACH SIDE than the daylight opening width up to 3348mm wide and 125mm each side on wider AA series doors. Optional Windlock guides require 145mm each side.
It is essential you calculate the total width required for installation purposes as it is wider than the ordering size!
See Table Below
| Minimum Clearance Required per side of structural opening for installation purposes - not ordering | ||
| Door Type | Manual Door | Automatic Door |
| Motor side only | ||
| 'A' series (up to 3400mm wide) | 90mm | 90mm |
| 'AA' series (over 3400mm wide) | 125mm | 125mm |

Height Dimensions Explained
Maximum guide height for Gliderol standard = 3000mm
Maximum overall width for Gliderol Door = 5000mm
Minimum overall width for Gliderol Door = 600mm
The Guide Height is also the reference for the Ordering Height for a Gliderol roller door -
It is the total height of the side guides that the roller curtain slides in and if you are ever in doubt about your height (i.e. unfinished floor, etc) you can order higher than required and cut the guides on site if necessary from the bottom and the curtain roll will simply take up the slack.
The amount of headroom required above the guide height is dependant upon the height of the door ordered, see table and diagram below:
Example: A floor to lintel height of 2150mm means ideally you would require 405mm of headroom and the ordering measurement would be 2150mm. If you don't have 430mm of headroom the roller door will still fit but you will lose drive through height when open. In the worst case of having no headroom at all then you will require a fascia cover of some description to cloak the roll from outside but your order height will be the total height less the roll size required. Always better to over estimate the height required with a Gliderol roller door as you can always cut the steel guides if they are too long.
The drive-through height is approximately 80mm less than the ordering opening height.
| Guide Height | Min. Headroom required for curtain roll |
| Up to 2100mm (6'11") | 430mm |
| Up to 2400mm (7'11") | 450mm |
| Up to 2700mm (8'10") | 450mm |
| Up to 3000mm (10'0") | 470mm |
