These Pillar Post System Essentials Kits provide the components to build rigid supports for optical systems. All kits include Ø1" posts, construction cubes, and post clamps, while the ESK15 kit also includes bases. The pedastal posts can be placed with freedom using clamp forks, while the pillar posts can be screwed directly into the table, stacked as extensions to other Ø1" posts, or attached to bases. All kits come with extra drawer dividers and the ESK21A/M comes with customizable labels. Refer to the Contents tab above for detailed comparisons of the components included with each kit. 

Mounting Options
The kits can be stored on a tabletop for easy, convenient access or placed on an RK4101 or RK4102 rack shelf, both of which can be installed in our RK3884 standard 19" rack. The image to the right shows an ESK15 kit as well as another custom-labeled S19909 cabinet installed in a 19" rack. The cabinet used in each Essential Series Kit features slots in the rear of the case (see image to far right) for wall mounting and features indentations on the top and four feet on the bottom for stable stacking. Warning: ESK15 (ESK15/M) weighs 47 lbs (21.3 kg) and ESK21A/M weighs 47.5 lbs (21.6 kg); ensure that the wall and wall mounts can support at least this weight before mounting the unit.

Each kit includes an S19909 9-Drawer Cabinet. In cases where the metric and imperial kits contain parts with different item numbers, metric item numbers and measurements are indicated in parentheses.

Smart Pack

  • Reduce Weight of Packaging Materials
  • Increase Usage of Recyclable Packing Materials
  • Improve Packing Integrity
  • Decrease Shipping Costs

Thorlabs' Smart Pack Initiative is aimed at waste minimization while still maintaining adequate protection for our products. By eliminating any unnecessary packaging, implementing packaging design changes, and utilizing eco-friendly packaging materials for our customers when possible, this initiative seeks to improve the environmental impact of our product packaging. Products listed above are now shipped in re-engineered packaging that minimizes the weight and the use of non-recyclable materials.b As we move through our product line, we will indicate re-engineered packages with our Smart Pack logo.

  • Travel-based emissions reduction calculations are estimated based on the total weight reduction of packaging materials used for all of 2013’s product sales, traveling 1,000 miles on an airplane, to provide general understanding of the impact of packaging material reduction. Calculations were made using the EPA’s shipping emissions values for different modes of transport.
  • Some Smart Pack products may show a negative weight reduction percentage as the substitution of greener packaging materials, such as the Greenwrap, at times slightly increases the weight of the product packaging.
