SELECT BY EQUIPMENT DEPTH

Two frame types solve two different installation needs.

Choose OF-2P when cable access, patching and shallow equipment are the priority. Choose OF-4P when deeper chassis, shelves or four-point mounting require a second support plane. The ordered configuration then defines anchoring, cable management, grounding and mobility.

OF-2P

CABLE-CENTRIC CONFIGURATION

2-post open frame

The efficient choice for patch panels, telecom, AV and shallow equipment where fast front-and-rear access matters most.

Simple, low-complexity structure
Clear cable routing and service access
Ideal for frequent moves, adds and changes

OF-4P

DEEP-EQUIPMENT CONFIGURATION

4-post open frame

Front-and-rear mechanical support for deeper chassis, shelves and equipment designed for four-point mounting.

Two support planes for deeper equipment
Better shelf and rail integration
Suitable for equipment-room installations

OPEN-FRAME ARCHITECTURE

Eight decisions behind a stable, serviceable installation.

2-post access

Low-complexity frame for patching, telecom, AV and shallow equipment.

4-post support

Front-and-rear mounting for deeper or four-point-supported equipment.

Primary structure

2.0 mm steel platform with model-specific assembly and finish.

Installation stability

Anchoring, stabilizers and center of gravity evaluated for the ordered load.

Cable organization

Vertical managers, lacing bars, rings and grounding can be coordinated.

Equipment support

Fixed shelves, support rails and brackets selected around chassis depth.

Mobility options

Heavy-duty bases, leveling feet or caster kits according to site use.

Project delivery
