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: each kit weighs 42 lbs (19.1 kg); ensure that the wall and wall mounts can support at least this weight before mounting the unit.

Hi, I've purchased more than twenty different kits from Thorlabs and would like to feed their contents into my inventory spreadsheet. It will be really helpful if you could include a spreadsheet of the contents of each as a support document. I paste below the chatgpt conversation I used to overcome this hurdle. Bard and HuggingFace failed miserably. Thanks, Lior ________________________ Good morning Chat! I would like to feed the contents of the LSB08-B kit into my inventory Google sheet. Here is its description: https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1125&pn=LSB08-B Could you please convert its contents to a list, as follows: First list out all the part numbers, starting with AC254-030-B-ML Then list out all the item descriptions, e.g. f=30 mm, Ø1" Achromatic Doublet, SM1-Threaded Mount, ARC: 650-1050 nm Then provide with me a list of product URL, starting with https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=3647&pn=AC254-030-B-ML Finally, list the quantities of each item. If unspecified in the said url, just write 1. Thanks! ____ That's actually incorrect, but let's retry on a different case. Could you please do the same procedure for https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=1314&pn=ESK16/M ? _________ I see that you are facing some difficulties accessing the information from the said link, so I'll just paste here. Could you please reorder it as requested? __________ That's match better! We're almost there (: Now, please omit the imperial part numbers and only keep the metric part numbers. For instance, replace 'TRB1 (TRB1/M)' with 'TRB1/M'. Similarly, replace 'Ø1/2" Optical Post, SS, 8-32 (M4) Setscrew, L = 0.75" (20 mm), 1/4"-20 (M6) Tap, 1" Stainless Steel Post' with 'Ø1/2" Optical Post, SS, M4 Setscrew, L = 20 mm, M6 Tap, 1" Stainless Steel Post'. If the part is universal, please keep it. For instance, keep the TRK05 and its description.

Thank you for reaching out to us with this request. This an interesting and creative way to use AI. I understand your frustration, and I have reached out internally in an attempt to provide such a spreadsheet document listing the included parts for these types of kits.

Response from Buki at Thorlabs.com Thank you for your feedback and your suggestions on how to modify the contents of our mechanics kits. We are glad to hear you find the kits useful and we will consider your suggestions on how to improve them.

These kits are great, but why don't they include any post collars? These are the accessory I use most of. I would also include 20 mm posts, and maybe anti-rotation adapters, and relegate the V mounts to the 'optical mounts' kit.
