Tower Racks
Tower Kits are the common vertical configuration for subracks and are available in multiples of 3U.
Multiple 3U sub-racks can be strapped together to form larger units by the addition of our Sub-Rack Joiner Kit. 6U, 9U, 12U, 15U.... the sky IS the limit.
Tower Kits can be supplied with either standard Rack Ears or the narrower profile Filler Ears.

Tower Rack Kits

All Towers are now constructed as multiples of a 3U Sub-rack. Simply select the quantity of sub-racks required and order one less Subrack Joiner Kit e.g. for a 9U system you need 3x 3U Subracks and 2x Subrack Joiner
Kits come with Rails, Tapped Strips, 160mm Side Panels, Back Panel, Rack Ears and assembly hardware.
All systems come with Rack Ears. The 84HP systems will fit in to standard 19" enclosures, the larger systems will requie custom 19" frames.
See the 'Clearance Corner' for some 6U Specials

Side Panels

Side Panels define the depth of the sub-rack and provide an optimally positioned rear mounting surface for busboards and power supplies. The industry standard depth of 160mm is provided here but we can also offer 220mm and 280mm deep Side Panels on request. Side Panels MUST be used with either our Rack or Filler Ears


Made from a high-quality aluminium they are irridium plated for improved electrical conductivity and anodised for a tougher surface finish and form the basis of any sub-rack. Each Rail has 1 x M5 tapped hole at each end. The addition of a Side Plate at each end allows the assembly to be secured from inside your enclosure. Rails have a slot towards the front to accept our Tapped Strips or Rack Nuts which must be purchased separately.
Other lengths up to 196HP available on request.
2 required per 3U section.
NOTE: Tower Rails are physically 1HP longer than the quoted module spacing

Tapped Strips

Tapped Strips slide in to a dedicated slot near the front of the Rail and are used to accomodate module fixing screws and are tapped to take M3 module fixing screws. The design of the Tapped Strip allows them to be end-stackable to make longer lengths than the standard 84HP length.
We can also supply M3 Square Rail Nuts and Tapped Strips with M2.5mm tappings.

Back Panels

Back Panels provide an ideal mounting surface for busboards and power supplies. In our standard Tower Racks this panel is 155mm behind module front panels allowing ample depth for deep modules

3U Ears

We offer 2 styles of Ear:-
1) Standard Rack Ears: These are the type used in conventional 19" enclosures and allow the sub-rack assembly to be quickly installed and removed. Rack Ears require an additional 55mm over the module width of the rack.
2) Filler Ears: If you do not wish to use the conventional rack mounting method and/or require a narrower housing then Filler Ears can be used in place of the standard Rack Ears. Filler Ears have a narrower profile that does not include the M6 mounting holes. The sub-rack assembly is mounted from inside the enclosure using suitably sized countersunk screws. Filler Ears require only an additional 20mm over the module width of the rack.
NOTE: Ears MUST be used in conjunction with Side Panel Spacers and cannot be fitted directly to a rail without them.
