可拆卸的扩展套件

The Saf-T-Notch Removable Extension is installed on ladders used to descend to lower levels or to ascend upwards through a hatch where permanent installation of an extension is undesirable. The kit extends the Saf-T-Notch Rail above the ground or roof level and allows the climber to attach to the Saf-T-Climb system before descending, or to remain attached to the system after ascending through a hatch. This insures the climber's continued safety when mounting or dismounting the ladder. When not in use, the extension can be removed so a manhole cover, hatch or grate can be replaced over the opening.

Removable Extension Kits come in Galvanized, Stainless Steel or Aluminum and can be ordered in two lengths for ease of use in either downhole climbs or uphole climbs. The Removable Extension rail for a is 4'6" long. The Rail for an uphole climb is 3'6" long.

Standard Saf-T-Notch rail: 4-1/2' length (or 3-1/2' for uphole climbs) with top 2' of guide channel removed to permit Saf-T-Lok Sleeve to turn 360°.

Tie Down Rod with either standard top knob or Quick Release: Assembly with rod threaded at bottom to attach to the Mandril.

Mandril: Permanently installed 6" inside of the top section of the Saf-T-Notch rail. Solid bar machined on both ends, drilled and tapped at the top, to accept the Tie Down Rod. Secured in place with two cap screws.

Use of one extension rail at multiple sites will require the permanent installation of a Mandril on each ladder.

Removable Extension Kits With Quick Release Tie-Down Rods

This time-saving feature facilitates the use of the Removable Extension Kit by several climbers who may be working at the same job site together, but who need to get on and off the same ladder at different times. The Quick Release Feature for Removable Extension Kits (as shown in the inset at right) replaces the knob at the top of the Tie-Down Rod. The device will allow easy mounting and dismounting of the Saf-T-Lok Sleeve onto the Extension Carrier Rail by multiple climbers on the same climb during the same work session. The spring-loaded lever pushes out of the way into the machined cavity in the device. Once the lever has been disengaged in this manner, the Sleeve will easily slip on or off the Extension Rail without the removal of the Tie-down Rod. When the pin is "at rest" (or fully extended) it will prevent the Sleeve from accidentally slipping off of the Extension Rail by itself.

The Removable Extension Rail and Tie Down Rod are portable and can be used on any ladder where a Mandril has been permanently installed. To use, slide the Saf-T-Lok Sleeve onto the Removable Extension Rail and place the rail over the Mandril on the ladder. Removable rail is secured to the ladder by tightening the threaded Tie Down Rod into the Mandril. The Saf-T-Lok Sleeve is then attached to the climber's Saf-T-Climb Harness while both feet are firmly planted on a solid surface. The climber pivots into position on the ladder, ready for descent, using the Removable Extension Rail as a safety hand hold.
