Aluminum Sleeve 18″ (for 1″ Ultra Poles)

For traditional pool fence installations on concrete or concrete-based surfaces, the standard 4″ deck sleeves included with All-Safe® pool fence sections are the best choice. However, when installing a pool fence on pavers or on surfaces built over a paver-style substructure (where no solid concrete slab exists beneath), extended sleeves are required. The same applies when a concrete deck measures less than 3-½ inches thick. In these applications, standard sleeves do not provide adequate depth or long-term stability. Using standard 4″ sleeves in pavers is a common installation mistake. While the fence may initially appear secure, pavers are not mortared or cemented in place and will shift over time. As movement occurs, fence posts—especially gate trusses and corner posts—lose stability, eventually leading to fence or gate failure. The 18″ Aluminum Extended Sleeve is an alternative solution for these conditions and is compatible with both 1-Inch Classic Pool Fence and 1-Inch Ultra Pool Fence pole systems. Do not use with Peg Pole fencing. Sleeve Dimensions:  18 Inches Long x 1.06 Inches (ID)   Why Aluminum Over PVC The aluminum sleeve offers superior rigidity and allows installers to use standard All-Safe® core bit sizes: Classic Pool Fence: 1-⅛” core bit Ultra Pool Fence: 1-¼” core bit PVC extended sleeves require an oversized 1-⅜” core bit, making aluminum the more efficient and professional choice. Installation Overview Once the hole is drilled: Hammer the aluminum sleeve through the paver and into the sub-surface. Set the sleeve at the correct angle for the fence pole or gate truss using a torpedo level or, preferably, a digital level. Drive the sleeve as deep as possible. Cut the sleeve flush with the deck surface. Installers should reference our YouTube tutorial: “How To Install a Pool Fence in Pavers” for best results. Additional Applications The 18″ Aluminum Extended Sleeve is also an excellent option for installations that require cement footers in dirt or grass. Its extended depth and rigidity provide long-term structural stability in non-deck environments. Alternative Options You can also opt to use a PVC Sleeve for Paver installations.
