Pre-Installation Information

The following is a general guide for installing the EVO-WA Wall Track Mount and includes basic instructions, positioning and tools required. Jaco recommends that you consult with a Structural Engineer prior to installing this Wall Mount Track. The wall construction, material, condition and sub-structure must be considered and failure to consult with an expert may lead to a compromised installation that is not safe and may cause harm. Jaco does not provide the wall anchor hardware and cannot be held responsible for improper installation.

WARNING: It is the responsibility of the hospital or facility, its consultants and/or contractors to determine that the wall is adequate to safely mount the Jaco Wall Arm Mount and Wall Arm. This includes the selection of appropriate wall anchor fasteners and proper, level installation.

Section 1. Tools and Parts Required

  • Level (critical that a level is used to make sure that the Wall Arm Bracket is level when installed)

  • Jaco does not provide the hardware or wall anchors needed, see section 3 for details.

  • Depending on what hardware is selected, tools needed may vary but typical tools needed will be a #2 Phillips screwdriver and hand drill.

Section 2. Wall Arm Placement

Typical positioning for the arm should place the user’s eye-level slightly below the top of the display. Depending on whether the arm will be primarily used in a standing or sitting position. With 15” of vertical adjustment, the Jaco Wall Arm Wall Track Mount should be installed 35” from the floor as shown below.

Section 3. Wall Track Installation 

There are several common materials used for wall construction including drywall/gypsum board, plaster coat over expanded metal lath, cement, or brick.   Selecting the proper hardware or wall mount anchors is critical and should be selected by a trained or qualified individual such as a Structural Engineer.  Jaco does not provide the mounting hardware for this reason, and it is the hospital or facilities responsibility to select the correct mounting hardware.


For selecting the proper hardware to mount the Wall Track, the exact location for the Wall Arm must be known and it must be determined if there are wall studs available within the wall.  If mounting into a wall stud, the (5) center mounting holes on the Wall Track, marked in the diagram as “A” below, should be used along with the correct hardware selected for this type of mounting.


If the mounting location cannot attach to an internal wall stud, the (10) outer mounting holes on the Wall Track, marked as “B” below, should be used with the proper hardware, such as toggle bolts.


You do not need to use all (15) mounting holes provided however you do need to use either (5) or (10) depending on the stud location.  If placement does not allow for centering on a wall stud but one outer row of (5) mounting holes happen to line up with the stud, use the stud mounting on that set of outside holes and toggle bolt mounting on the other (5) holes for a total of (10) mounting holes.


As noted in Section 1, it is critical that a level is used to make sure that the Wall Arm Bracket is installed level so that the Wall Arm does not lean left or right.  Failure to do so will void the Wall Arm Warranty. 

Section 3. Cont.

Mounting on Drywall/Gypsum Board Over Wood Studs or 16 Gauge Steel Studs: 

  1. Locate the building stud in the area and align the center holes of the track to the center of the wood stud.
  2. Use a level to make sure the track is vertical and mark the locations on the wall through the holes centered on a stud. 
  3. Remove and put the track aside.
  4. Drill 3/16” diameter pilot holes into the wall at the marked locations.
  5. Once all holes are drilled, secure track to the wall by fastening the screws through the middle holes and into stud. 

Mounting on Drywall/Gypsum Over Steel Studs Less than 16 Gauge: 

  1. Locate the building studs in the area and align the center holes of the track to the center of the studs.
  2. Use a level to make sure the track is vertical and mark the locations on the wall through the holes centered on a stud.
  3. Remove and put the track aside. 
  4. Drill 11/16” (1.75 cm) diameter holes into the wall at appropriate vertical spacing.
  5. Once all the holes are drilled, insert the 3” long, 0.25”-20 pan head machine screws into the track and insert into the toggle wings. 
  6. 6. With the track upright, align the toggle bolts to the drilled holes and insert into the studs. 
  7. Tighten the screws to secure the track. 

Section 4. Wall Arm Mount Unboxing and Installation 

The Jaco Wall Arm is delivered on a pallet and unpacking is a two-person task, please plan accordingly.  Use caution when removing any additional containers that may have shipped on top of the Wall Arm pack. There will be minimal assembly required as Jaco products are shipped fully assembled. 


Upon opening the box, you will see that there is a divider between the accessories and the main assembly.  Please refer to the image below. 

Consult with a Structural Engineer before mounting the Wall Track.  With your wall location selected and the correct mount hardware available, you are ready to start.  The Wall Track is symmetrical so either end can be placed up or down but must be mounted in a vertical position and precisely level. There are 3 sets of mounting holes for flexibility, but most applications will require that Wall Arm be mounted in the lowest position.  The Wall Track should be mounted so that the bottom is 35” from the floor.  With the bottom 4-position mounting holes for the Wall Arm, the top 4-position mounting holes should be used for the optional PC holder if required.

After securely mounting the Wall Track to the wall, pre-install the top two and the bottom left screws in the low Wall Arm mount position. Only install into the holes halfway to allow the Wall Arm Mount Bracket to slide into position.


Carefully slide the Wall Arm mount onto the top two and bottom left screws as shown in Figure A so it rests in place and then install the bottom right screw tight before tightening the remaining 3 screws.

With the Wall Arm main assembly attached and secured, you should attach the LCD to the VESA plate, hardware is provided.  Also attach any additional accessories you may have purchased such as the PC Holder, scanner mount, signature pad holder, etc.  

Once the LCD and options are in place, check and ensure that the side tension knob is in the locked position. Knob should be turned clockwise 

CAUTION: The LCD must be mounted to the VESA Plate before starting next step.

Use a Phillips screwdriver and tighten the screw shown. This will actuate the piston assembly.

With this actuation screw set, the Wall Arm can be height adjusted by loosening the Side Knob, grasping the sides of the Keyboard Enclosure and lifting or lowering the Wall Arm into the position needed for proper use.  Tighten the Side Know once the Wall Arm is in this position.

Section 5. PC Holder Mount and Cable Management 

Jaco offers a variety of PC holder mounts as an optional accessory that mount directly to the wall track to keep your technology compact and cables out-of-sight and out of the way. PC mounts are available in either locking or non-locking depending on your workplace needs.

The PC Mount or Tech Box is mounted at the top of the Wall Arm track with cables routing through the bottom of the box, down through the track cable cover and are then routed through the arm itself up to the LCD or monitor for optimal cable management.

Connect your Monitor power cable and VGA/DVI/HDMI cable to your Monitor. Route these cables through the dress cover as shown above. Cables will route through the post conduit and up the mounting rail to the PC shelf. Connect these cables to your PC.

Connect the keyboard and mouse USB cables to the Hub mounted inside the keyboard enclosure. The USB hub cable is then routed behind the enclosure and goes into the conduit on the post. Continue routing up the mounting rail and into PC shelf.
