Support Locations- Cable Tray
(Reference: NEMA VE-2 Current Issue)
Supports should be located so that connectors (splice joints) between horizontal runs fall between the support point and quarter point of the span. The Support Span should not be greater than the straight section length. Snap Track tray and other TechLine Mfg. tray comes in standard 20’ lengths.
Single Hold Down Clamps
TechLine Mfg. Hold Down Clamps are available in aluminum or hot dipped galvanized.
Hold down clamps are used to anchor Snap Trap or other cable tray to a structural element. They are typically installed when the physical structure prevents or makes it difficult to use the hole pattern of the cable tray.
Installation Guide: When installing Hold Down Clamps, two (2) clamps should be used and attached to each side rail.
Installation Guide: Snap Track cable tray should only be anchored to Snap Track supports, directly to the structural members, or to other supporting systems with Snap Track hold down clamps at the midpoint between expansion splice. At all other supports Snap Track expansion guides should be installed to allow for thermal expansion and permit longitudinal movement from the anchor or fixed point – NEMA VE-2 (Current Issue).
