Prior to our invention of Wittclip^TM fasteners, most drop in liners were secured in tanks using drawstring rope. The problem with rope is that it doesn't securely lock the tank liner to the rim of the tank. When the tank is filled with solution the liner can be pulled into the tank a bit, greatly affecting how the liner fits. The larger a liner is, the more pronounced this problem becomes.

To solve this issue, Witt Lining Systems invented the Wittclip^TM fastener. Wittclips are u-shaped stainless steel clips with a threaded bolt welded on one end. Wittclips securely hold the liner to the lip of the tank so that when the tank is filled, rather than pulling the liner into the tank, the weight of the solution pushes the tank liner flush to the sidewalls making for a perfect fitting liner.

We have twelve styles of Wittclips to handle most any tank rim configuration. We have different leg lengths to handle different rim sizes and clips with varied distances between the legs to handle rim thicknesses up to 2 in. thick. We also have a clothespin style Wittclip that can be used on tanks that have no rim at all.
