Attaching the rack to a 9 - 13 in. or 12 - 22 in. floor
Use these steps to attach your rack to a 228.6 mm to 330.2 mm (9 in. to 13 in. depth). floor.
Attention: The frame tie downs are intended
to secure a frame weighing less than 1429 kg (3150 lb). These tie
downs are designed to secure the frame on a raised-floor installation.
Use the following to determine your next step:
- If the rack is being attached to a short-depth raised-floor environment
228.6 - 330.2 mm (9 - 13 in. depth), install the Raised floor tie-down
kit (part number 16R1102) described in the following table.

Note: To accommodate a floor with a depth of more than
558.8 mm (22 in.), a steel beam or a steel channel adapter for mounting
the sub-floor eyebolts are required. The customer must supply the
floor eyebolts.
Consider the following when preparing the
floor for tie-down procedure:
- The hardware is designed to support a frame weighing no more than 1429 kg (3150 lb).
- The estimated maximum concentrated load on one caster for a 1429 kg (3150 lb) system is 476.3 kg (1050 lb). For a multiple-system installation, one floor tile might bear a total concentrated load of 952.5 kg (2100 lb).
To install the eyebolts, do the following steps:
- Obtain the service of a qualified structural engineer to determine the appropriate installation of the eyebolts.
- Consider the following before installing the eyebolts:
- Floor eyebolts must be securely anchored to the concrete floor.
- For a single-frame installation, four 1/2-in. diameter by 13-in. sub-floor eyebolts should be secured to the sub-floor.
- The minimum height of the center of the internal diameter is 2.54 mm (1 in.) above the concrete floor surface.
- The maximum height is 63.5 mm (2.5 in.) above the concrete floor surface. A height greater than 63.5 mm (2.5 in.) can cause excessive lateral deflection to the tie-down hardware.
- The eyebolt's internal diameter should be 1-3/16 inch, and each eyebolt should be able to withstand 1224.7 kg (2700 lb). The customer should obtain the services of a qualified consultant or structural engineer to determine the appropriate anchoring method for these eyebolts and to ensure that the raised floor and the building can support the floor-loading specifications.
- To ensure that the holes are in the correct location, the diagonal distance of the center of the holes should be 1211.2 mm (47.7 in.). The distance between the center holes to the center of the next holes should be 654.8 mm (25.8 in.) (the side-to-side distance) and 1019 mm (40.1 in.) (the front-to-back distance).
- Verify that the four eyebolts are positioned to match the dimensions
in the following figures.Figure 1. Eyebolt positioning for 610 mm (24 in.) floor tile layout

- Install the eyebolts to the floor. The service representative
can now install the frame. Figure 4. Turnbuckle assembly frame tie-down hardware for 228.6 - 330.2 mm (9 - 13 in.) raised floor (part number 44P2999)
