Installation Instructions - Updated as of  08/30/12 

Step #1

Position the spa cover (in closed position) on the spa making sure that all four corners 
are properly positioned and square on the spa.

Step #2

Using the #10 x 1-1/2” Mounting Screws, attach the Left and Right Mounting Brackets to 
the appropriate sides of the spa (

See Fig. 1

).  

Note:  the brackets can be mounted directly 

on the top rail of the spa or to the sidewall of the spa.  Caution:  to prevent splitting of 
wood cabinets, pre-drill holes with a 1/16” drill bit.

Step #4

Starting with the left side first, lay the long end of the Support Arms on the top of the 
cover, lying parallel to the spa cover hinge about 1/2” away.  Slide the U-shaped 
retainer clip between the two cover halves with the horizontal part touching the 
underside of the cover hinge (

See Fig. 3

)  

Note:  Do not insert the U-shaped retainer 

clip in between the seams of the spa cover.

  With the left Support Arm lying on the 

cover, slide the Center Coupler piece over the long end of the left Support Arm.  Next, 
slide the long end of the right Support Arm into the center coupler and slide the 
U-shaped retainere clip between the two cover halves.

Step #5

Slide the left and right Pivot Arms onto the short end of the Support Arms (

See Fig. 3

).  

Note:  Do not insert the self-tapping screws at this time, this will be completed in step 
#7.

  Next, connect the Pivot Arms to the Mounting Brackets (

See Fig. 4

).  Be sure to run 

the Hex Cap Bolts as pictured.  

Note:  Lightly tighted the nut so the Pivot Arm moves 

freely.

Step #6

Next, install the Ball Studs to the Left and Right Pivot Arms.  Place the two Hex Dome 
Caps over the Ball Stud Lock Nuts.  

Note:  be sure that the ball is pointing away from 

the spa (See Fig. 5).

Step #7

With the Center Coupler and Support Arms adjusted properly (About 1/2” away from 
the cover hinge and centered on the spa), use the #10 X 5/8” self tapping screws to 
fasten the Support Arms to the Pivot Arms and the Center Coupler to teh Support Arms 
(

See Fig. 6

).  

Note:  be sure to rotate the Center Coupler so that the inserted screws are 

at a horizontal angle with the screw head facing the back of the spa.

Step #3

Install the Wind Lock Bar on the determined bracket side (

See Fig. 2

).  

Note:  Lightly 

tighten the nut and bolt combination so that the Lock Bar moves freely.

Step #8

Using the Covermate, lift the cover off the spa and place it in the upright position.  
Snap the gas shocks on to the Ball Studs.  

Note:  be sure to install the Gas Shocks with 

the black body on top.

  (

).

Step #9

Attach the 3/8” Rubber Sleeve to the end of the Pivot Arm that the Wind Lock Bar 
latches on to (

See Fig. 8

). 

 

Step #10

Attach the provided 3 hook Towelmate on the preferred side of your Covermate by 
simply snapping it in place and inserting the middle 5/8” Self-Tapping Screw (

See Fig. 9

).
