Gondola Shelving Installation Guide

Gondola shelving assembly follows a fixed sequence: base components first, uprights second, rails third, back panels and shelves last. Deviating from this sequence creates rework, back panels cannot be installed after shelves without removing the shelves, and rails cannot be set at correct height after uprights are loaded. This guide covers the standard installation sequence with notes on leveling, connection verification, and load checks before the section carries product.

Tools and Preparation

Standard tools: rubber mallet, torpedo level, tape measure, and an adjustable wrench for leveling-leg bolts. Most Lozier gondola connections are tool-free snap-fit -- no power tools are required for standard assembly. A second person is required for upright placement on sections 72in and taller. Work from a clean, clear floor area, product should not be on the floor in the installation zone.

Assembly Sequence

Step 1: Snap a chalkline. Establish the run alignment on the floor before placing any component. Every subsequent placement references this line. This is Step 1 in the Lozier install manual.

Step 2: Position and level Base Brackets. Set Base Brackets at the correct section spacing (24in, 30in, 36in, or 48in center-to-center per the section width you specified). Lozier Base Brackets include integrated leveling legs, use those before reaching for shims. Verify level in both directions across each bracket, and across the run using a level or string line spanning the top of the brackets.

Step 3: Set Uprites onto Base Brackets. Each Uprite has front and rear tabs that engage the Base Bracket. Press firmly and verify both tabs are fully seated. Sections 72in and taller require two people. Uprites use a 1in-on-center slotted perforation pattern (not keyhole slots).

Step 4: Install Top Rail. The Top Rail sets the final upright-to-upright spacing for the section. Measure the spacing at the Top Rail before locking the connection, this determines whether shelves at full depth will fit correctly on both sides of the Uprite pair.

Step 5: Install Bottom Rail. Bend the Bottom Rail tabs as documented in the install manual's Step 5 detail before seating. The Bottom Rail resists outward spread at the base under load and is required on both Island and Wall sections per the Lozier catalog.

Step 6: Install Center Rail(s). Every Lozier Island and Wall section requires one Top, Center, and Bottom Rail. Sections 96in-144in tall with a back panel require two Center Rails (not one). Verify the count on your BOM before ordering, a short-ordered second Center Rail is the most common back-panel BOM omission.

Step 7: Install the lower Back Panel only. For two-piece backs on taller sections, install the lower Back first with a Splicer Rail set over it. Do NOT install the upper Back or remaining Backs yet. The install manual specifically warns: "Do not install remaining Backs yet!" at this stage, leveling must be completed with only the lower Back in place.

Step 8: Level the run with a string line. Stretch a string line tightly between the end Uprites using a leveling leg wrench or wedge placed in the same slot on each end Uprite (Step 8.1 of the manual). Find the highest Uprite in the run (the one with the most slots above the string line). Adjust that Uprite's leveling leg down until the string line matches the same slot as the end Uprites (Step 8.2). Then use a carpenter's level on the face of each Uprite and adjust the Base Bracket leveling leg with a screwdriver to plumb it (Step 8.3). For Wall Sections that will be anchored to the wall, the manual recommends a rearward Uprite tilt of about 3/4in.

Step 9: Anchor Wall Sections and free-standing sections. Anchor Base Brackets of all free-standing Wall Sections regardless of Uprite height to leveler spacing ratio. If a run of wall sections is longer than 12ft, temporarily install two continuous levels of shelving before anchoring the Uprites to the wall to verify the center-to-center spacing is correct. Failure to do this can result in shelves that do not fit correctly or at all.

Step 10: Install remaining Back Panels. With the framework leveled and anchored, install the remaining Back Panels. Refer to the Back Panel size chart in the install manual (page 4) for the correct back panel size for the section height.

Step 11: Install Shelves last. Set shelf hooks into the Uprite slot at the specified height. TL (Tilt-Level) shelves hang horizontally. DL (Down-Level) shelves angle at 17° or 30° depending on hook position. Verify each shelf is level side-to-side before loading product. The manual warns: "When installing or rearranging shelving, never move assembled shelving."

Common Installation Errors and Cited Warnings

• Installing all Back Panels before leveling. The install manual explicitly instructs: "Assemble remaining framework along chalkline. Do not install remaining Backs yet!" Backs installed before framework leveling force a partial disassembly to complete the leveling procedure.
• Missing the second Center Rail on 96in+ back sections. The Lozier catalog specifies: "96"H-144"H Backs require two Center Rails." Ordering one Center Rail on a 96in back section produces a section that cannot support the back correctly.
• Retrofitting Slotwall backs into low-ceiling spaces. The Lozier catalog specifies Slotwall backs require 60 inches of clearance above the shelving to install. In stores where ceiling height above the fixture is less than 60 inches, Slotwall cannot be installed and Pegboard or Marteck should be spec'd instead. This is a common retrofit failure that shows up on install day, not in the plan review.
• Skipping the string-line leveling procedure. The manual's Step 8 leveling procedure uses a string line pulled tight between end Uprites, with each interior Uprite adjusted to match the same slot on the string. Level-by-eye or level-per-Uprite is not the documented procedure and produces cumulative slot mis-registration across a long run.
• Combining Lozier and non-Lozier parts. The manual states: "Do not combine Lozier products with non-Lozier products."
• Using damaged parts. The manual states: "Never use damaged parts. Damaged parts may cause shelving to be structurally unsafe or create exposure to sharp or pointed edges." Damaged shipments should be reported to Lozier customer service before install.
• Not anchoring free-standing Wall Sections. The manual states: "Anchor Base Brackets of all free-standing Wall Sections regardless of Uprite height to leveler spacing ratio." Free-standing sections that are not anchored per this instruction are vulnerable to overturning.
• Exceeding allowable load limits. The manual states: "Do not exceed Allowable Load Limits. Exceeding allowable loads may cause the shelving to tip over or collapse." Unbalanced load calculations are documented on pages 5-6 of the install manual.
