The [[Pouch Attachment Ladder System|PALS]] grid is made up of repeating horizontal rows of {{Convert|1|in|mm|abbr=out|sp=us|adj=on|disp=}} tall [[webbing]], alternating off with 1-inch tall empty space. The stitched lines (specifically [[Bar tack|bartacks]]) help create a horizontal opening of {{Convert|1.5|in|mm|abbr=out|sp=us}} to feed a pouch attachment strap through.<ref name=":3">{{Cite web |title=Pouch Attachment Ladder System |url=https://ciehub.info/equipment/loadbearing/PALS.html#gsc.tab=0 |archive-url=https://web.archive.org/web/20120813020851/http://loadbearingequipment.ciehub.info/PALS.html |archive-date=13 August 2012 |access-date=14 May 2025 |website=ciehub.info (clothing and individual equipment) |quote=The Pouch Attachment Ladder System is a grid of webbing that consists of rows of heavy-duty nylon stitched onto load-carrying platforms such as backpacks and vests. This system attaches items through the "inter-weaving" of webbing between the item to be attached and the platform to which it is being attached. (_enter_); To properly attach an item, choose the desired attachment point on the platform. Line up the top of the item even with the top of the nearest horizontal 1 inch webbing that goes across the platform. Insert the attachment strap on the item down the 1.5 inch channel on the platform, then behind the 1 inch webbing on the back of the item. Continue weaving the attaching strap behind the horizontal webbing on the platform and the webbing on the back of the item until the item is secured along its entire length. (_enter_); This attachment system is extremely secure and stable when used properly. (_enter_); Do not simply place the attaching strap through the platform webbing without the interlocking weave. The items will not be secure if attached in this manner.}}</ref>

When two separate sides of PALS webbing are met, the empty space of one side is taken up by the webbing of the other side, allowing for a filled interface. The interface's requisite to horizontally align allows a channel to open, through which an anchoring strap can feed and occupy. The positioning of the pouch's anchoring strap prevents either pouch- or base-side from slipping away, and is chiefly responsible for its interlocking ability. Concludingly, the pouch anchoring strap is itself locked down by a [[snap fastener]] at the fly-end/loose end of said pouch strap, on the rear of the pouch, via [[Snap fastener#Gallery|socket]] and [[Snap fastener#Gallery|stud]] components (respectively).<ref name=":3" />

PALS measurements (for 1 inch webbing):

* 1 inch tall webbing
* 1 inch gap, alternating with the prior piece
* 1.5 inch wide insert loops (for pouch attachment straps)

The height of the webbing is 1 inch or 25.4 mm, with a tolerance of ± {{Convert|1/16|in|mm|abbr=out|sp=us|disp=or}} — equivalent to {{Convert|0.9375–1.0625|in|mm|2|abbr=out|sp=us|disp=}}.<ref>{{Cite web |date=15 November 1996 |title=A-A-55301 (Base Document) - Webbing, textile, textured or multi-filament nylon |url=https://milspecmonkey.com/materials/A-A-55301.pdf |url-status=live |archive-url=https://web.archive.org/web/20250315045833/https://milspecmonkey.com/materials/A-A-55301.pdf |archive-date=15 March 2025 |access-date=13 May 2025 |website=milspecmonkey.com |pages=1, 3}}</ref> In other words, the height of webbing can be off by about half of 1/10th an inch, and still remain within tolerance. In metric, the tolerance is within roughly 1.25 mm on the low end and roughly 2.00 mm on the high end.

The misalignment of divider bartacks in 1.5 inch insert loops is considered acceptable within approx. {{Convert|1.4–1.6|in|mm|abbr=out|sp=us|adj=}} wide.{{citation needed|date=February 2020}}
