PRODUCT DESCRIPTION 

General 

The patent pending GridLOK extended referencing system is a versatile locating system 

based upon the positioning of conical seats installed in a concrete floor or in an optional 

steel plate. Each of the conical seats is permanently flush mounted and valued by a laser 

tracker. 

The system’s software utilizes mathematical algorithms to recognize which 

locations have been probed in order to automatically perform a reference into the grid’s 

coordinate system. There is no need to input any positional or X, Y & Z data while 

referencing or relocating. 

This system is much more accurate than the leapfrog method since all point locations 

are known and there is no accumulative error when relocating within the measurement 

volume.

Any ROMER arm(s) can be used with the GridLOK system without any mechanical 

or electrical modifications. The GridLOK system allows the user to easily move 

around the measuring volume and take measurements inside or out of a vehicle or 

assembly. 

GridLOK System Components 

1. Portable arm support stand with laptop holder 

2. GridLOK Positioning Software 

3. Grid system, installed by ROMER technicians in concrete slab (or optional steel plate) 

Concrete Slab Floor - conical seats are installed into a single concrete pad in a 

predetermined grid pattern. Conical seats are permanently flush mounted to the 

pad. Each conical seat comes with a removable protective cover. 

The size of the measuring area is determined by the customer’s specific measuring 

requirements. 

Steel Plate Option - conical seats are machined into a steel plate of sufficient size 

and strength to support the item(s) being inspected. The steel plate is then installed 

at the inspection site. 

The size of the measuring area is determined by the customer’s specific measuring 

requirements. NOTE: Steel plate sold separately.

Mobile Arm Stand with Laptop Support 

This portable cast iron rolling post stand provides 

solid support for the ROMER arm with the added 

capability of easy transport around the 

measuring volume of the GridLOK System. A 

laptop tray is included with the mobile arm stand 

to support the system’s laptop computer. 

The stand includes a universal mounting plate 

designed to support all varieties of ROMER arm 

mounting systems including a magnetic base. 

The stand's three 2-inch casters with rubber tires 

can be retracted into the base by a foot pedal. A 

seamless steel tube with clamping collar and 

braces from the base provide additional rigidity 

ensure stability. The height of the stand is from 

23" (fully retracted) to 39" (fully extended). The 

stand weighs 200 lbs. 

Floor Based Grid System 

Either a single concrete slab or an optional steel plate can be used to set up the grid 

system. Once the desired measuring volume has been determined, the appropriate 

number and position of target points will be laid out on the concrete slab or steel plate.

Conical seats, which act as targets, are then permanently installed to the slab. 

After the conical seats have been installed, a laser tracker is used to establish the target 

positions and provide a master data list that will be used to load the site map for the grid 

reference coordinate system. 

There are no electrical, mechanical or moving parts associated with the grid system; 

therefore there will be essentially no system downtime or required maintenance. 

GridLOK Positioning Software with Grid Referencing Ability 

All referencing is performed with ROMER’s GridLOK Positioning Software. No additional 

software is required and no lengthy or confusing external programs must be run to 

complete the grid reference. A straightforward user interface ensures no additional 

training when performing a grid coordinate reference.
