Frequently asked questions

Questions before installation

Still unsure? SPI Supply can help verify the kit before you order.

Ask a product question
How do I choose the correct inlay depth?

Measure the total finished thickness of the material that will sit inside the cover, including the adhesive or setting layer. Match that measurement to the depth chart above, then choose from the options available on this product.

Can a HIDE cover be installed in an existing deck?

Many HIDE covers can be used for retrofit projects. The opening dimensions, clearance, finished surface thickness and site conditions must be checked before ordering or altering the deck.

Should a professional install the cover?

Professional installation is strongly recommended. Have a licensed, suitably experienced contractor read and follow the applicable installation instructions before work begins; incorrect installation can affect warranty coverage.

What is included with a HIDE kit?

Kit contents vary by cover model and selected depth. Review the product-specific “What’s included” list above, the product description and the applicable technical documents before ordering.

How should the cover be cleaned and maintained?

Remove accumulated debris and clean the exposed surface appropriately for the surrounding finish. Do not allow acid or chemical-wash solutions to contact the stainless-steel components, and always store the safety key securely away from children.

Overview

The HIDE HSL12 is a 12" square, inlay-ready skimmer lid system that blends your pool deck surface into a flush, near-invisible access cover. Each variant matches a specific surface thickness and uses either a single-key (shallow depths) or double-key (thicker inlay) design for secure lifting. Ideal for pool surrounds and other exterior access points where a clean, premium finish is desired.

What's Included

  • Inlay Cover (tray) – accepts your deck material (tile/stone/paver/turf/concrete as applicable)
  • Edge Protector frame
  • HIDE Safety Key (single or double, per depth)
  • Height Adjuster (5 mm / 3⁄16")
  • HIDE Adhesive tube (for assembling the inlay cover)
  • Homeowner Info Pack (manual)

Compatibility & Replacements

Compatible with most deck finishes—tile, stone, pavers, turf, and (with specific kits) concrete wet-pour. Select the variant depth that matches your installed surface. For concrete applications, choose thicker kits (typically 1.6", 2.0", or 2.5") that include the conversion needed for wet-pour installs.

Installation & Notes

  • Professional installation recommended; follow HIDE’s contractor instructions.
  • Never leave the Safety Key in the lid; pass it to the homeowner after install.
  • Do not expose stainless components to acid/chemical washes (will stain/void coverage).
  • Bonding/earthing must follow local codes; attachment points are provided if required.
