H-Channel

The H-channel is used between two shades for blackout applications. The mounting surface 
of the H-channel has grooved lines for easy drilling and for reducing the need for a center 
punch. The opposite side of the H-channel is smooth. Plugs are available to conceal holes 
in the channel. Use a 3/8" drill bit for the plugs.

U-Channel

The U-channel is used on the sides of shades for blackout applications. The U-channel 
comes in 2-1/2 in (64 mm) and 1-1/2 in (38 mm) widths. The mounting surface of the 
U-channel has a grooved line for easy drilling and for reducing the need for a center punch. 
The opposite side of the U-channel is smooth. Plugs are available to conceal holes in the 
channel. Use a 3/8" drill bit for the plugs.

Channel Cap

H-channels and U-channels come with caps to provide a clean finish on the cut ends. The 
channel caps can fit the 2-1/2 in (64 mm) or 1-1/2 in (38 mm) channel widths. The channel 
caps press into place. Four channel caps come with the H-channel; two channel caps come 
with the U-channel.

CAUTION

:  The channel cap must be used on the top of the H-channel or U-channel in 

order to prevent damage to the shade fabric.

Sill Angle

The sill angle is used for blackout applications by preventing light leaks along the bottom of 
the shade. The sill angle is used in conjunction with a blackout hembar. The side of the sill 
angle contains a grooved line for easy drilling and for reducing the need for a center punch.

Wool Pile

The wool pile comes in two sizes. Small wool piles are installed in U- or H-channels and 
large wool piles are installed in pockets. The wool pile is used to help block light from a 
room. When ordered with the shade, the wool pile is typically preinstalled in the U- or 
H-channel and pocket.
