An installation tool that is used to install a bundling member, such as a metal tie or strap, around a bundle of objects. The installation tool has a tool body, a front handle and an adjustable rear handle. The front handle is positioned within the tool body and the rear handle is pivotally connected to the tool body. The front handle includes a tensioning mechanism with a ratchet mechanism that tensions the bundling member around the bundle of objects to a predetermined tension setting. The front handle also includes a lockout mechanism that overrides the predetermined tension setting of the tension mechanism to enable the bundling member to be tensioned to a desired tension setting.

The invention claimed is: 1. An installation tool comprising: a tool body; a front handle positioned within the tool body, the front handle having a tensioning mechanism disposed therein, wherein the tensioning mechanism includes a ratchet mechanism for tensioning a bundling member to a predetermined tensioned setting; wherein the front handle includes an adapter having arms with a channel therebetween and the ratchet mechanism includes a ratchet housing positioned within the channel, the ratchet housing having sides with a groove formed in a bottom edge of each side; and a rear handle pivotally connected to the tool body. 2. The installation tool of claim 1, wherein the front handle houses a spring tensioned plunger adapted to engage the ratchet housing, wherein the plunger has a flange with a channel therein for housing a detent roller that engages the grooves in the bottom edge of the ratchet housing, whereby when the front handle is actuated the detent roller forces the ratchet housing to rotate until the bundling member reaches the predetermined tension and the detent roller detents out of the groove of the ratchet housing causing the ratchet housing to remain stationary. 3. The installation tool of claim 1, wherein the ratchet housing includes a ratchet wheel with a plurality of teeth, a driving pawl for advancing the ratchet wheel and a holding pawl for preventing the ratchet wheel from unwinding. 4. The installation tool of claim 3, further comprising a mandrel positioned through the adapter, the ratchet housing and the ratchet wheel, whereby when the ratchet wheel rotates, the mandrel rotates winding the bundling member positioned therein. 5. The installation tool of claim 1, further comprising a cutting mechanism pivotally connected to the tool body, wherein the cutting mechanism includes a rotary cutter for cutting the bundling member and a cutting lever arm for controlling the rotary cutter. 6. The installation tool of claim 5, wherein the tool body includes a nose having an outwardly extending housing with a cavity for housing a portion of the cutting mechanism. 7. The installation tool of claim 1, wherein the tool body includes an outwardly extending finger guard for controlling the cut bundling member as the bundling member uncoils. 8. An installation tool comprising: a tool body; a front handle positioned within the tool body, the front handle having a tensioning mechanism disposed therein for tensioning a bundling member to a predetermined tensioned setting; a rear handle pivotally connected to the tool body, the rear handle including an adjustment mechanism for enabling the rear handle to be adjusted to various positions with respect to the tool body, wherein the tool body includes at least one shaft for supporting the rear handle and adjustment pins for locking the rear handle as the handle pivots; and wherein the rear handle includes a stamping with two upwardly extending arms and a channel therebetween, whereby when the rear handle is attached to the tool body, one of the arms is positioned between inner sides of the tool body and the opposite arm is positioned adjacent to an outer side of the tool body. 9. The installation tool of claim 8, wherein the upwardly extending arms include a plurality of opposing holes for receiving one of the adjustment pins. 10. The installation tool of claim 8, wherein the upwardly extending arms include a central hole for receiving the shaft extending inwardly from the tool body. 11. An installation tool comprising: a tool body; a front handle positioned within the tool body, the front handle having a tensioning mechanism disposed therein for tensioning a bundling member; a lockout mechanism positioned within the front handle, the lockout mechanism overriding a predetermined tension setting of the tensioning mechanism to enable the bundling member to be tensioned to a desired amount; and a rear handle pivotally connected to the tool body. 12. The installation tool of claim 11, wherein the lockout mechanism includes an arcuate portion for engaging a flange of a spring tensioned plunger disposed in the front handle, whereby the lockout mechanism prevents the spring tensioned plunger from compressing in the front handle. 13. The installation tool of claim 12, wherein the lockout mechanism includes at least one side opening for receiving at least one pin disposed within a slot in the front handle, whereby the at least one pin slides within the at least one slot for enabling the lockout mechanism to slidingly engage the plunger disposed in the front handle. 14. An installation tool comprising: a tool body; a front handle positioned within the tool body, the front handle having a tensioning mechanism disposed therein for tensioning a bundling member to a predetermined tensioned setting; a rear handle pivotally connected to the tool body, the rear handle including an adjustment mechanism for enabling the rear handle to be adjusted to various positions with respect to the tool body, wherein the tool body includes at least one shaft for supporting the rear handle and adjustment pins for locking the rear handle as the handle pivots; and a spring positioned on the at least one shaft of the tool body.
