The square cover — or rectangular — closes any right-angled opening, flat or as a low pyramid.

Source: Grille de Puits. ## Square, rectangular, genuinely bespoke This is the model where “made to measure” really earns its name: there is no standard dimension for a built well. The frame is 40 × 8 mm flat bar cut to the exact size of your structure, the bars are 14 mm solid square section, spacing 9 cm maximum. Two profiles: flat (flush, like the flat model) or low pyramid (≈ 20 cm rise), which sheds water and stops anything being stored on it. For large cisterns and chambers the cover is made in two or three panels assembled on site — each panel remaining liftable by two people. ## Cisterns and spring heads Vaulted cisterns and spring heads raise one extra question: periodic access for inspection, pumping or cleaning. The standard answer is a hinged, padlockable central panel set into the fixed frame — the rectangular equivalent of our lockable model. State the use on the quote request: a rainwater cistern used every week is not closed the same way as a chamber opened once every five years. ## Same manufacture, same guarantee Solid iron, full welds, hot-dip galvanising, finish colour of your choice: the square cover follows the same specification as the whole range, twenty-year guarantee included. Stainless fixings and fitting instructions are supplied; fixing into old masonry is done with resin anchors, never with expansion bolts, which split tired old mortar. ## The right profile for the use Choosing between flat and pyramid comes down to one question: does anyone walk over it? On a spring chamber or a well beside a path, the flat version sits flush and can be crossed safely. On a built well in a courtyard or ornamental garden, the low pyramid has more presence, sheds rainwater and discourages people from parking pots and tools on it. On very large cisterns, the hinged central panel turns the fixed square cover into a lockable inspection hatch — the rectangular equivalent of our lockable model. Simply tell us how the structure is actually used when you request a quote: that, not aesthetics alone, dictates the right profile. Frequently asked ## Square well cover: your questions Do you make very large sizes for cisterns? Yes, as assembled panels: each panel stays liftable by two people. Beyond 2 m a side, quoting is done from a drawing or dimensioned photographs. Pyramid or flat: how do I choose? Flat if the opening is on a walkway (you can step on it); pyramid everywhere else — it sheds water, refuses loads and looks better on characterful masonry. Can the cover be fixed without drilling the stone? On listed or fragile structures we replace the anchors with a counterweighted frame that grips the masonry — zero drilling. Mention it on the quote and the workshop adapts.
