8.3.10  Fixing Cabinets 

I. Installing the T-shape nuts 

Before fixing a cabinet, put T-shape nuts into the upper troughs of the slide rails, two on each 
side. (Each anchor strip needs two T-shape nuts).  

II. Installing anchor strips 

As shown in Figure 8-36, install the anchor strips (two for each cabinet). 

  Caution: 

The anchor strips must be installed in the orientation as shown in Figure 8-36.  

 

 

1) Retaining nut of anchor strip 

2) Cabinet foot 

3) Anchor strip 

Figure 8-36 

Install anchor strips 

III. Installing insulating parts and fixing anchor strips 

Follow these steps to install insulating parts and fix an anchor strip: 

1)  Put the insulating washers under the anchor strip and align them vertically with 

the T-shape nuts in the upper troughs of the anchor strip (one anchor strip needs 
two insulating washers).
